Carburetor adjustment for Homelite 2 cycle engine The product doesn't start easy, and it does come to full throttle. If I run it on partial choke it runs fairly good, but it has been getting worse. Last time I used it, it was difficult to start. By the time I was finished using it, it was running at about 1/2 throttel. The product is only 6 months old and runabout 4 times. Repairman told to buy a Packman carb tool, but I need to know the corrrect adustment. Repairmans description of adjustment was a little fuzzy. Can you help

    Your right it does sound a little too asy, but your comment makes sense. I would like to know the correct adjustment on the craburetor. I don't think it was set right from the factory, it should have run perfect on the run position and it never did. I had to run it on partial choke from the start. That is a clear message to me it was not set correctly.

    Now it is getting worse, so something has been happening to make it run worse. I am concerned that it could get worse so quickly, I only used it about 5 times. Maybe my gas can had dirt in it, I can clean it and get fresh gas. How else woul I get plugged up fuel lines like you are describing in such a short time.

    Let me know if you have aditional suggestions

    The previous comment is incomplete, I am really looking for the correct carburetor adjustments for this machine. I will take the other person advice and try the carb cleaner, but I find it a little hard to believe the fuel line is jammed up on a tool I only used 5 times. The machine has two carb screws that can be adjusted. One person told me I need a Packman tool for this machine. Okay I can get that, but I think I would like to know the correct adjustments, I don't want to repeat this request for diagnostics every time the machine doesn't work right.

    Okay it is pretty obvious you guys don't have clue. Please refund my money or I will report this to the credit card company. To refund my money you can send a refund to the credit card I used or you can deny the charge on my card.

I have the same problem with my MightyLite 26cc Blower/Vac. If it does start it runs rough on full choke and stalls on 1/2 choke or run. I've tried everything, fresh fuel, Seafoam, etc. Nothing works. First time I used it the exhaust burned a hole in my brand new Carhartt hooded sweatshirt. Best solution, throw it away, never buy another Homelite product and tell anyone who will listen what a piece of junk Homelite products are.

I am a tech I also had this problem of miss adjusted carb from the factory. EPA does not want everyone to do this. But I did buy the tool because I have a shop The kit comes with 4 drivers which include the Packman driver(about $40 for the set) to adjust the carb. Gently seat the adjustment screws and back them out 1 to1 1/2 turns. Start engine and readjust both for idle and Hi Speed. I did have to cut some off the handle of the driver to clear the blower on the BP.

It is starving for fuel. If it was running good when you bought it and you have not adjusted the carburetor, then why would it need adjusting now? Go out and purchase a can of Seafoam Engine cleaner at almost any Auto Parts store. Pour 1 ounce in a full tank of fuel. Start the engine and run it. You will see an improvement very quickly in how it runs. I know this sounds too easy, but I have seen this work time and time again. There is an obstruction in the fuel supply somewhere. The Seafoam will clean out the fuel system. Now if this does not work, which I suspect it will, turn the carb power adjustment very slightly counterclockwise. Barely turn it while the engine is running. You will know when it is right. If none of this works then the carb must be removed and disassembled.

Have a Mighty Lite Backpack Blower. Same exact problem. First few times it ran decently, never really could rev to a decent level. Might be running lean since I had to keep the choke on partially.

Only used about 4 or 5 times and now it won't stay running for more than a moment and can't rev at all.

Would like to adjust the fuel to air ratio, but there are two pac man style carb screws. How do these get adjusted?

Drain gas from machine. Run carb cleaner through carb. Mix fresh gas at the correct mix ratio, be sure it's the right ratio!

Try lightly seating but watch how many turns it was out then turn fuel needle back out the same amount,then start the unit and adjust from there,if you still need to run with choke partially on, the carb needs cleaning you can try using carb cleaner on while its running,if that doesn.t help you may need to remove and dismantle to clean completely

I have a Homelite Easyreach Model # UT20044A that will start, but then dies. Cleaned the filter, spark plug but still dies


Check that the carburettor and fuel lines are clean. If the unit has not been used for a while the gas (petrol) will evaporate leaving the oil behind to choke up the fuel system. Dirty fuel will do the same. When adding fuel use a funnel with gauze filter in it and always empty the fuel tank and then run the motor until it dies when you've finished work.

Hi how to tune homelite 330 chain saw carby, idle


Before adjusting anything, check the fuel filter, air filter, and muffler for plugging. Check the condition of the fuel lines for decay or other damage. Tighten all carburetor fasteners. Make sure you have fresh fuel mix in the tank. Does the primer bulb pull fresh fuel into itself when pumped? Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and should allow the engine to start and run. Start the engine and allow it to warm up, then pull the throttle full on. Adjust H needle CW until the engine starts to speed up, but still 4-stroking. Proper final adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW for fairly good idle, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

You should have taken advantage of the warranty when you first noticed the problem. Go to: http://www.drystacked.com for an excellent 12 page article on Walbro carburetors--theory and troubleshooting. Note carefully, the caution about the lower chamber gasket and diaphragm positions. Hot running engines imply very lean fuel conditions. Hopefully, you haven't damaged the inner cylinder liner/piston/rings due to excess heat and lack of lubrication. At 50:1 fuel ratio, there isn't much lubrication to spare. Make sure the carburetor fasteners are tight and no plugging of the fuel filter. The head and cylinder are one casting--no head gasket. Try turning both jet screws CW to the stops (lightly), then back out each CCW 1-1/2 turns. This is a basic setting and the engine should start and run. Allow to warm up, then pull the throttle full on--adjust H needle CW until the engine speeds up, but continues to 4-stroke. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. This produces the most power and least heat. Allow to idle and adjust L CW until the engine runs fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw to stop the chain from turning, but keeps the engine running. Hope this helps!

If the fuel tank was completely full, I would expect fuel leakage from the tank vent--don't make a practice of overfilling. Give it a little breathing room for expansion. Check the air cleaner and muffler for plugging. White and red adjustments mean nothing to a color blind person. There should be an 'H' and 'L' cast into the plastic surface or on the carburetor body itself near the adjustments. Turn both screws CW to stops (lightly) and then back out each 1-1/2 turns CCW. Start the engine and allow to warm up. Pull the throttle full on, and adjust H CW until the engine starts to speed up but still 4-stroking. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Release the throttle and adjust L CW until the engine runs fairly well, but allows the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Carburator adjustment for Homelite xl 12 chain saw


Turn both screws CW to stops (lightly), then back out each CCW 1-1/2 turns. This should get the engine running if it will. If it does not, check the lower diaphragm on the carburetor for hardness or cracking. You appear to be running on prime only--the carburetor doesn't seem to be pumping in fresh fuel. You may need to do a carburetor clean and re-kit. Check the fuel line condition and the fuel filter in the tank for plugging. Make sure the muffler and air cleaner are not plugged. Once you get the engine to continue running, warm the engine up. Open the throttle and adjust the H needle CW--the engine should start to speed up, but still 4-stroking. The proper setting is 4-stroking, but immediately 2-stroke when cutting. Release the throttle and adjust L needle CW so that the engine runs fairly smoothly, yet will allow the engine to 'follow the throttle'. Set idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Engine does not continue to run


Are you laying off the choke at any point? Full choke should only be used when starting a cold engine, it should run with no choke on full throttle. If there is not enough throttle i'd first try adjusting the tiny black screw on the carb beneath your air filter while you have it idling, letting the throttle have a little bit more room. If this doesn't work and you're running it properly than you may need to make some adjustments to the H L settings for your gas/air mix. This is also done while idling mind you and only with a clean air filter.

How do I adjust needle valves on a 25cc Homelite UT08111A Backpack leaf blower?


Set the lowend & highend needles to about 1 3/4 to 2 turns each. Choke the carb or prime it, until the carb is wet. Fire up the engine and let it warm up. Let's set the topend first since it's the easier of the two. Go to full throttle. Adjust the topend needle for peak RPM. Leave it wide open for about a minute to see if it changes any. Should the engine go lean, open the lowend needle slightly, if this dosen't work... you will have to adjust the needle valve inside the carb.( I will explain this later) If the topend runs OK, then slowly pull the throttle down until the engine begins to "four cycle" hold the throttle there. Adjust the lowend needle until the "four cycling" barely stops. Now lower the throttle more until it "four cycles" again, and adjust the lowend again. Keep doing this until you reach full idle. Now, from full idle begin to throttle up until the engine starts to bog or hesitate. Open up the lowend needle just enough to eliminate the bog or hesitation.

Gas leaf blower runs at half speed


First you will have to get a carburetor kit ,it consists of diaprams and inlet needle,you then remove the two srews that hold carburetor on the engine and remove gas lines,also the throttle cable remove screws that hold ends of carburetor on under these you will find the diaphrams and needle remove these be carefull not to loose the little spring under the needle lever.
!get you a can of carburetor cleaner and spray carburetor the blow it out with air you will notice little jets in carburetor that have to be clean use a wire from a bread tie to clean them out install new gaskets and diaprams in same position you took old ones off.you can also look at carburetor to see what kind it is walbor,zama,tilloson? type the name in google search and can get a diagram of carburetor if you loose your place,or just ask me.

Homelite 2-cycle gas line-trimmer - It starts okay but when you hit the throttle it dies.


The high speed jet is either out of adjustment or it is plugged. There should be a screws with H (high speed) and L (low speed, idle) You could try to open the high speed adjustment on the carb or run your machine on partial choke if you have to.
