My 359 almost wont four stroke,
Firstly it just wouldnt four stroke at all, even with needle valve almost all the way out.. an after 2-3 turns out it stops making difference.
Cleaned carb, replaced both diaphragm and membrane raised metering valve a bit, now it barely four strokes at full throttle.
needle valves do not make any significant difference, acceleration seems sluggish, im 99% that it doesnt leak on crankshaft seals(new oem seals)
Idle Needle doesnt make a difference until given throttle and i cannot really kill it by richening too much on idle valve.
Also it doesnt seem to be leaking air, can be easily killed with choke, just like perfectly working one.
Edit: rpm doesnt change a bit from rotating a saw in any direction
What do you guys think? Is it carb problem? I cannot really get new one in this time, so if its atleast temporary fixable it would be good.
