Hey there peeps! I haven't been posting on the board for quite sometime, but a need has arisen.
Somewhat recently as a result of changing exhaust on my 150cc gy6 the exhaust bolt stripped the threading on the head...I took this as an opportunity to bump up to a performance cylinder head and a14 camshaft.
Everything went extremely well until it came time to crank it up...it basically laughed at me initially and then i realized i hadn't tightened the nuts on the rocker arm assembly to specified torque...all good. Valves adjusted to .004 and .005. She started up with a hedonistic raucous sound! Beautiful!
But, she wouldn't stay running...Now its been extremely difficult to keep her running without giving her some juice...I adjusted the a/f ratio and saw some improvements...but getting her to crank on the first go round and keeping her running has been a chore...
My thoughts are that it may be that I simply need to upjet the main and slow jet on the carb...any thoughts or ideas?
