After fixing every possible air and fuel leak I can think of by rebuilding the carb, replacing the fuel and impulse line and doing a compression test (150psi) this saw refuses to tune. No matter what i do it dies with throttle, idles funny and seems to run extremely rich at times even at 1 turn or less on both the low and high jet. I haven't done a pressure test on the carb as i dont have a tester though its on my wishlist. The carb is a Walbro 22b I believe. I don't feel like pulling it off to check but I am pretty sure that's what it is. Any help would be greatly appreciated. Im getting pretty tired of tearing this thing apart.
