ok this has got me confused, as ANY motor should run with a loose flywheel let alone a flywheel on it at all. the Flywheel has NOTHING to do with your engine running, and the ONLY possible reason i can imagine is if the LOOSE FLYWHEEL is a. holding the front bearing inplace, therefore creating a seal by holding the bearing inplace so when loose your getting an air leak in the front of the crankcase, OR b is BINDING up with another part putting stress or pinching and stopping or dragging on the crankshaft.. so which is it, cuz I KNOW a loose flywheel is NOT stopping the flow of nitro or stopping the glow plug from holding heat..

So what do you THINK the reason is... at this point the ONLY LOGICAL thought is it is helping to create a seal by holding the front bearing in place. which is not only a Bad Design but a BAD IDEA to begin with... so.... im a bit amiss. Speak to me Peeps. Dont this kind of make you go ***?????

it does me and i dont even have the problem yet...
