Before adjusting the jet screws to fix something caused by other factors, look for a clogged fuel filter, air cleaner, or muffler. Check the condition of the fuel lines and the fasteners on the carburetor. Make sure the primer button is soft and not cracked. These saws use a Walbro brand carburetor and an excellent article on troubles and repair can be found at: http://www.drystacked.com The pictures are out of focus and he neglects the pumper chamber action, but the theory is very helpful--especially the position of the lower chamber gasket/diaphragm. Hope this helps!

How do i set air on husky 435 saw to fix boggy runnin


Mitch:

Adjust the fuel and air mixture screws while the saw is running... you'll find that "sweet spot"... it just takes a little patience! Small adjustments... If you over adjust and the saw quits running or starting, GENTLY turn both screws in all the way (don't damage the needle valves or seats) and turn both out one and a quarter (1 1/4) turns out. The saw should start, then adjust from there.

Set the carb for a mcculloch 3516 chain saw


Carburetor Adjustment
There are no hard and fast settings.
A good initial starting point for the "H" and "L" needle valves are 1.5 turns CCW from lightly seated.
The "T" adjustment enters here (idle speed) and there is no initial setting without a tachometer, depending on age of your saw there may not be any initial "T" setting.
The "L" needle is primarily idle performance (not speed) and acceleration to full throttle.
The "H" is mostly performance at speed, but all are interconnected.


Start with a fresh mix of fuel. Put ALL of the old mix in any 4 cycle engine and start new. I suggest 50:1 regardless of what your manual says.
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; once 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.
Now we adjust for performance. The best performance adjustment procedure I have found follows.
Madsens Shop & Supply, Inc. Carburetor adjustment (All saws homeowner and professional are the same)
http://www.madsens1.com/saw%20carb%20tune.htm Read step 4 (allow it warm before making adjustments).
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 is often indicative of a larger problem.
If push comes to shove a local saw shop (I prefer Stihl mechanics and do not own a Stihl) should be considered.

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

Most chainsaws die because they are are run lean. I am going to inject a little Lou theory here. 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.
