i jus instaled a new motor in my friends blaster i didnt start it yet because i need to premix oil ...but the clutch lever is so easy to pull and the arm on the crankcare i can move with my one finger and i never could do that on ne thing elas...does it need a new clutch or do i have to adjust it somehow?

 

Sounds like clutch springs. Take off the clutch cover and see if the springs are still there.

 

Any updates?
