Check the oil level. If the oil is low, the chipper will not continue running.

Hi jim gabriel

Sounds like you have dirt/debris in your caburetor jets,fuel passages
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note:Before you disassemble the carburetor:
Write down on a piece of paper or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of chainsaws and weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor or take a pictue for later reference.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Make sure you are using fresh fuel...and oil if your using a two cycle chainsaw or weedeater with the oil to the right mixture...too much oil as it can cause hard starting and excessive smoking.
If the chainsaw/trimmer is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
The little spring inside of the carburetor goes under the float arm.
That is where your fuel inlet needle/float valve is located...on the arm at the end.
Normally there is a small indention in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.
The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.
Once you have your carburetor cleaned/rebuilt that should solve your problem.

How much oil should be in troy built cultivator

Check the dip stick on level ground. Clean it off and reinsert it. The dipstick has the mark for correct amount. If you see it coating whole stick, it is way overfilled,

If not.......Your filter can possibly be plugged and the heat in the crankcase is creating pressure that pumps some of the oil out the filter. Get a new filter or clean it out. Might need oil change to get rid of dirt or sludge

I am having a hard time getting my carburetor adjusted for my Troy Bilt 2 cycle tiller

First you need to repair the fuel inlet properly. You likely have an air leak the way it is now. You can get a replacement inlet elbow at your local parts shop. Tecumpseh and briggs are a bit different but look very similar so be sure what you have before you go. grab hold of the brass with channel locks or vice grips and pull straight out to remove the old one. Put a dab of oil on the new one, align the way you want it to face and press in firmly. Do not twist or it will break again.
Once the inlet is repaired properly then you can adjust the carb. The low speed jet is the one closest to the motor. The initial settings are 1 and a half turns out for both low and high.

Troy-bilt cultivator 26cc gas/oil separate engine spewing oil out through filter when running...there is a hose from the oil reservoir straight into the back of the the engine revs it literally...

Hi, Check the oil reservoir breather that it's not plugged up. The oil should be returning back to the reservoir not going to the filter. That tells me that there is air being pumped into the engine (oil).
The piston rings could be broken or the carberator needs to be readjusted.

Open the air screw abit more on carb. Then see what happens. Good luck.

Oli spils when lawn mover starts

Check your oil level in the engine, normally if oil starts coming out of the air filter, it means you have too much oil in the crankcase. Drain your crankcase to make it the right level, be sure to check you oil level in the engine on level ground. I hope this helped, Good Luck Please rate me, Thanks

Troy built cultivator will only idle 26cc 5yrs old

Problably not sucking air, but not getting enough air. Does your cultivator use gas/oil mix or straight gas? If it is a gas/oil mix the muffler is probably stopped up with carbon and cutting off the air flow. Try removing the muffler and see if it runs better.
