I have an 025 with a fixed H jet Carb. According to the service book it says - -
"This carburetor has a fixed jet in place of the high speed adjusting screw (H screw). Maximum engine speed is preset and no longer adjustable. It is only possible to correct idling speed within certain limits. The carburetor guarantees and optimum fuel-air mixture in all operating conditions."
The saw sounds lean - very lean when running. It is running almost 15,000 rpm by tach. The specs for this saw are 13,000 for saws w/ the adjustable carb. I'm going to vac test it to rule out and air leak. Is there any way to make the saw run richer without replacing the carb?
