Ive just installed a os 18tm into my revo and went out to break the engine in. I fitted the flywheel, clutch shoes and clutch bell on correctly as per traxxas exploded diagrams but when i start the engine to run it in the crankshaft and flywheel spin but the clutch bell isn't and the truck doesn't move at all. Ive idled thru the first tank of fuel.

Can anyone help me?

Thanks
