There is a recall on the UT models, all you have to do is call the costumer service center for homelite. they will give you a number for the closest warrenty center that will adjust you throttle cable free of charge. I went through two UT 10520's before i started researching the problem.

I had the same problem 2 weeks ago. I figured out that the way the cable is engineered, it is holding the throttle open. I actually found that if I pushed down with my knee on the hande and wiggled it, While spraying WD-40 in the cable. Eventually it freed up, and started working right. This saw was assembled in China, and is a prime example of why we should not allow stuff to be made there. The quality is very bad. I have an old 16" XL that still starts better than my new UT10520. I bought the new one because I liked the old one so much. That will teach me. Now I am having a problem with starting it at all, and the manual says "Contact an authorized service center for carburetor adjustment." I should have paid more money and bought a Sthil.

I had the same problem. I had to shorten the cable sleeve and it works great. Now all I have to do is find the stock adjustments for the high and low on the carberator. Had to cut slots into the adjusment screws.

Homelite UT10520 Chainsaw runs wide open. It is not in the throttle. The carburetor is clean as a pin and there are no leaks. It must be in the electronic timing module. I just do not know how it is timed.

Same problem-fixed by opening handle and engine cover, getting access to both ends of throttle cable and spraying motorcycle cable-lube into cable body. After some new adjustments to throttle speed screw, it runs like it should from Homelite. Never buy Homelite again.

It wont stay running after i get it started


That means that it is not getting enough fuel to the carb. Check your tank for fuel and the hose and filter inside. Make sure all the hoses are attached right and are not broken or leaking.

Also close the adjustment carb screws all the way in. Then open them one turn back to start . Try to start the saw. Then make adjustments to the low adjustment screw. If any of these don't work try a known working carburetor. See if that makes a difference.

Need owner or service or both manuals for Homelite model #UT10516


Robert:

As far as the manuals... you might be able to download them at http://www.homelite.com. (you can click on the link) under customer service, you'll find "owner's manuals). To adjust the fuel/air mixture, start the saw and turn the adjustment screws in or out a little at a time until you get the saw running properly. There is no "set" adjustment... as the saw motor ages, those settings will change. If you make adjustments to the fuel/air screws and the saw stops running and starting, turn the adjustment screws all the way in (clockwise) GENTLY... If you force those screws you will damage the needle valve seats! Turn both screws out one and a quarter turns out, and the saw will start. continue adjusting until the saw runs properly. Have patience... it may take a while to get the saw running to your satisfaction.

Chain saw stalls


hello sir,, now there are two types of carb.adjustment screw covers,the old one where there are plastic over the screws,simple remove the plastic covers with a pair of needle nose pliers or cutting off,,,second are the new ones that are above the adjustment screws,which you have to take your drummel tool with the cutting blade and cut slots in the screws, after you get this done it is important to count the number of rotations in until stops make note how many. because you are going to reset the same way.now remove the screws,put to the side when you get ready to put screws in put in all the way than back out as many turns that you noted, now that is factory set there should only be a small adjustment to do. the rule of thumb is turn both out 1 1/4 turn and adjust in until saw runs smooth and idles ok, it is hard to adjust the top speed when saw is running wide open,let saw idle when adjusting top speed is easier that way, when you go to cut wood you may have to readjust top speed, the above does apply some what if you are not using fresh gas mix and dumped out the old fuel and starting with fresh,and a new plug CJ8Y,and as you know the saw has to breath in and out by this i mean a clean air filter,make sure the small screen on the muffler is not cloged,this will keep saw from running at peak speed and sawing wood, ok i have ran across a few saws to where the small screen in the muffler is cloged so the saw would idle but not run at high rpm's,if you do and check all of the above your saw should run,oh btw check compression should be above 60 to 160 lbs, hope this helps,any comments welcome,thank you. 00

Messed up carburetor


Start out with both screws at 1-1/2 run saw full throttle and adj. screw closest to air filter, which should be "H" screw it in slowly till you reach max rpm's then reverese the screw just till it starts to slow down, keep in mind don't take forever to do this cause you don't want it running lean (max rpm's) because it will COOK in no time! After you have the high speed set let saw Idle, then accelerate quickly, if it bogs turn the "L"" clockwise little at a time reving it each time, till you get the bog worked, then when acceleration sounds quite responsive then go back to H speed and readjust it, open it up some and run it wide open and readadjust H speed to where it just drops off on rpms on the rich side not lean side, righty (leany)...Lefty Richy ! Good luck

I need to tune up my saw but I can't find my owner's manual. It won't idle. Need to know how to adjust the low speed. It runs well but my low speed idle won't adjust to make it keep running.


The theory is much the same on all chainsaw carbs, start and warm the machine up, increase the idle speed with the idle screw if it will not tick over, start to turn the L screw in, the revs will increase as the mixture leans off, it will reach a point where it is too lean and start to die, at that point turn the screw out 1/4 turn, check it revs up clean, if not turn screw out bit at a time until it does, now set the idle speed with the idle screw. Before attempting this make sure the fuel filter is clean, and also the air filter.

Need gas/oil mix for Homelite 330 10604A, HJ


To the best of my recollection the 330 is an older model saw and should be running about a 16:1 ratio. 8oz. of oil to 1 gallon of fuel. Hope this helps.

Note: You're always better being a bit richer (lower ratio) than you are leaner (higher ratio).

My homelite chainsaw model# ut10520 has aoil leak from the flexible line at the base of the oil tank.


I input your model number and found 3 possible matches, "42cc/46cc Chain Saw UT-10520; SUPER 2 Chain Saw UT-10520 or SUPER 2 Chain Saw UT-10520-A".
I opened the first "Ref # 3" on "Figure A" I suspect is what you say is leaking. It is very inexpensive and available. I would order one and inspect it once recieved to determine an installation method. It does not appear overly difficult without the part in hand. Good Luck.


Homelite/Ryobi.com (authorized parts supplier)
https://www.gardnerinc.com/recons/disclaimer-lg.php - Agree; Choose “Product Line”; “Select OEM” & “Select Catalog” both to “Homelite Consumer Products”. A drop down list appears; self explanatory from here.
The numbers Homelite & Ryobi use do not match the numbers everyone posts. A careful inspection of your saw should find something that matches.

GETTING MY HOMELITE 150 STARTED.


Hello Vic;
Start with “L” & “H” needle valves 1.5 CCW from lightly seated, then adjust for performance as follows.
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm
  • CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
  • Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
  • Clean the spark arrestor and muffler; if the saw cannot exhale it cannot inhale.
  • There are 2 wav (sound - idle & full - may not be highlighted) files that I find most helpful, I think you will too.
I am going to inject a little philosophy here. Undetected air leaks and defective fuel delivery systems account for most chainsaw failures. Constant adjustment of needle valves can easily camouflage more serious problems that result in burning up your saw. A sudden need for an adjustment may be indicative of a larger problem.

I searched for an OM with no good luck. Please contact them here:
Homelite.com (Contact Us)
https://register.homelite.com/contact_us/new
Ask they create an on line location where OMs can be found and down loaded please.

If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck.

Chainsaw only runs when i take off the air filter and keep it at high revs,as soon as i take finger of the trigger it cuts out and wont idle.ive already cleaned out the carb,checked fuel,cleaned filter and...


It sounds rich to me try turning the "L" needle CW a little. CAUTION CW is leaner, to lean will destroy your saw. Adding the air cleaner leans out the mixture. Adjusting it with the air filter off can cause a run lean condition when installed.
