Valve adjustment on a Lb1p57qmj motor HELP

[RyanosAlien]

Hey,

I own a longbow alien 150 cc scooter and is in need of a valve adjustment, does any 1 know what the lb1p57qmj motor needs to be adjusted to, I don't know if this would change any thing but I have a couple aftermarket mods on it : Performance cdi & coil, uni filter, koso clutch, 12g weights, 1500 lbs clut ch and main springs, 30mm intake manifold , "30mm carb in mail be here Tom or mon", 118 main jet.

Stupid scooter will roll over but not start, only thing that might be a issue is I added the upgraded manifold recently but it ran perfect for past week with the install, but now it will start if I hold throttle wide open.

Any ideas???

You can take down this post, I set the valves to .004 and .005 and couldnt get it to start so I thought I did something wrong and it turned out to be the cdi.....
