Almost finished project but rear wheel locked up!

[netsky9]

Hi there

I have put together all the parts of a chinese 70cc kit, but have found that the rear wheel locks up moves. With the spark plug removed it rotates, but as soon as it goes back on then the same problem occurs.

What should I do? any help/advice/suggestions hugely appreciated.

Cheers!!

well how about you do a little research on why a motor needs compression to run... after you do that try pulling in the CLUTCH!!!!

Sorry I should have mentioned that the clutch does not have any effect at this point!

Thanks for the feedback, still looking for answers

going to need you to pull of head and take pictures of inside the cylinder with piston all the way at the top and also of the underside of the head with your sparkplug tightened
