Help with my scooter

[cameronpatton38]

I have a 49cc scooter I bought a 100cc bbk but decided not to put it in yet so I put the original back and it won't start at all. My flywheel won't even turn the slightest. My rockers arms are set .004 top and bottom. Is it too tight?? I've also checked the motion of the rocker arms and valves it looks like it get a stuck in the middle and doesn't rotate the chain or anything

Do you have a manual? That will give you the specs for valve lash.
It sounds like you put something together wrong if it doesn't turn. Disassemble and reassemble again -- use your manual!
