So imma start from the beginning of my problems, and if you dont care, skip ahead to the bold letters
So i bought a 2014 576xp 2 years ago, sparkplug threads were stripped out without realizing, thanks ebay... and the carb was bad, did the top end and put a new carb 350$ down the drain, ran like a dream.
My first post on here was due to problems of it not tuning, did a vac/pres test, was bad crank seals, fixed it, tuned it in and got the top rpm set, that was during the beginning of northern winter.
NOW THIS damn time, started it in 2 weeks ago, figured i had a bad adjustment, reset it to factory setting 1.5 and 3 straight out the manual, fired it up again today and rich in the low, could tune it and hear the bog when over rich, hit the high and whine right out coil hits the limit, held a tach to it reaches 10,500 then the saw goes lean as hell and whines out and the coil limit hits.
Figured an air leak, took the carb off, plug and exhaust to check everything over, upper ring and crown has a score along with the upper cylinder on exhaust side. Obviously crud got in there, did the pres/vac 8psi and -10 inHg didnt drop one bit, shook the intake manifold and same, didnt drop.
i need some help solving this if anyone can help before i go huck this junk saw off a mountain side
