I found out the problem. By the way this motor isnt a max version, its a big block. I found the exploded view for the motor off of nitrohouse.com. For some reason picco decided to make there own special one way bearing that goes inside the the motor. I think its a stupid and inconvient design cause now i have to buy their bearing and i cant use the one thats pictured.

Heres the exploded view off a picco .27 engine to show you what i mean:

You can see how the pullstart axle is different and that is what through me off.

thanks anyways
