Give Sam a call at Hawkins and Milnor in Shelbina Missouri. THey specialize in older homelite parts and they have the intake boots made to factory specs. The material is of better quality and is not old, rotten NOS parts that have been on the shelf for years. They are a pain to change in the first place. Might as well put a good one in and do it once.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Adjust the low-speed adjustment screw on the left and high-speed adjustment screw on the right with a screwdriver. Turn the low-speed screw clockwise until you feel the needle touch the seat. Turn the low-speed screw back counterclockwise one and one-third turns.
If the carburetor is new or has been rebuilt, you should set it to “factory” adjustment. You can do so by adjusting the idle mixture screws to 1.5-2 turns out, and the idle speed screw to 1-1.5 turns in. Warm the Engine Up. The engine`s running temperature directly correlates with proper air and fuel mixtures.
Turn the high speed or main jet screw clockwise until the engine begins to slow. Then, turn the screw the other way until the engine begins to slow. Turn the screw back to the midpoint. Once adjusted, check engine acceleration by moving the throttle from idle to fast.
Find the adjustment screws on the front of the carburetor
There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.
If your engine turns over or cranks, but doesn`t start, it could be due to a dirty carburetor. When there`s too much dirt in the carburetor, the required combination of air and fuel can`t travel through the passage to the engine, causing a turn over, but no catch or actual start. It`s running lean.
The ideal chemical air-fuel ratio, in which all the fuel is oxidized, is 14.7:1, that is, 14.7 parts air to 1 part fuel.
Application of carburetor heat will decrease air density, causing the RPM to drop even lower. Then, as the carburetor ice melts, the RPM will rise gradually.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.

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.

Replace bar and or chain …saw runs but not with the chain
The bar MUST be straight. Soak the chain with penetrating oil. If that doesn’t free it up, replace it. If it is kinked sideways–replace it. Never run a chainsaw with damaged parts.
I just started up my new 16″ Homelite and the engine starts, but the mechanism that powers the chainsaw isn’t rotating… any suggestions?
The engine needs to be accelerated to make the chain turn. The chain should not be so tight on the bar that you can’t turn it by hand. Make sure the chain brake is off by pulling back on the brake paddle which has a ‘toggle’ effect–it should snap over to the new position. If still having problems, it is time to return for warranty exchange or repair. 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!
