Hi
I reassmble my YS-110FZ after replacing the bearings, and piston ring but the engine dosen't want to work...

i wasn't able to start it at all but then after many attempets i finally managed to start it but the engine was running at low r.p.m for few seconds ( no matter what was the throttle position ) and then it dies

i tried it severall times but it was the same oncwe the engine start it works for few seconds and then it die..

it looks to me that the engine is starving for fuel but after those few seconds of working there was perssure on the tank when i release the check valve

any ideas ?

Thanks
