Fixing up a 245 SA and have replaced fuel line/filter and rebuilt carb with kit. Checked reeds are OK and carb and reed gaskets good and sealed. Saw will not tune out on high and won't Idle well either. Am I looking at main seals? Anything else? How do you check?

Thanks

What do you mean by "tune out on high"? Are you trying to tune it at WOT to the point where it doesn't burble/4-stroke at all? DON'T tune it that way. It will lean out in the cut and damage the engine (and bog down). Also, that saw has a governor in the carb that makes it richen out when it revs past a certain point. Best way to tune these is to set the L and H needles to about 1-1/4 turn out, then cut with it. You can lean the high side out a bit so it just cleans up when loaded in the cut. Don't lean it much past 1 turn out however. Are the carb diaphragms fresh? That saw has a Tillotson HS carb that takes an RK-23HS kit. If you haven't rebuilt the carb yet, you might as well do it now.

Also, go to the Poulan thread in the "chainsaw stickies" sub-forum. Much more likely to get help there.
