Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Be sure to check the fuel filter, air cleaner, and muffler for plugging. Start the engine and allow to warm up--pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is reached when the engine 4-strokes at speed, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but will allow the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

Solo 662 chainsaw carburetor adjustment


most non professional grade or smaller saws are only adjustable by re jetting the carb. if they are adjustable there will be a low, high and idle adjustment on the side of the carb, however unless you have a portable tach and know the rpm limits or are experienced doing it "by ear" i wouldnt suggesting messing with it as youll more than likely burn up the power head.

Most of carburetor has three buttons to adjust. L (low), H (high) for fuel injection at low and high speeds. There is also a minimum (the chain must be stationary if it is well tuned). The chainsaw is set at low rpm throttle with screws ( L ), and its vivacity is set at high speeds ( H screw ). In the beginning is good put both to set at 1.5 turns from full closure. And then, if the chainsaw starts, you can adjust a carburetor work. Careful with adjusting with H due to high speed.

How do you adjust the carborator on a 2.5 stihl chainsaw?


Most Stihl carburetors built after 2000 have limiter caps that prevent much adjusting. the standard for adjustable carburetors is 1 turn out on both high and low then set rpm of idle and high end to specs.

If you need to adjust the engine to get it running there is a problem somewhere else in the systems.
see a dealer like www.arcolawn.com for help.

good luck

The default setting for the H and L carburetor jet is usually to turn them in all the way till they stop and back them out a turn and a half. You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. turn the low adjustment screw out. You will notice that the rpms should start increasing. keep turning it out until the rpms start to drop then turn it back in a quarter of a turn. You may need to readjust the idle speed so the chain doesn't turn during idle. Do the same for the high adjustment screw.
