Nah it's one I bought and couldn't get it to run, I've previously posted about it, I could never get it to run. The only thing I could think of was it could have been the crank seal, but didn't want to go to the trouble to get it off. That said, there's scoring on the piston, so at this point I'm not going to bang my head against the wall with it any longer.

However, the chassis is really good and alloy, and I have a spare PT engine that works but has a short shaft/boss. I was hoping to remove the crank and boss from each engine and swap them, then put the spare known good PT engine with the newly fitted long crank onto the body, I just wanted to know if the crank can be swapped between bodies or if there's something that would stop me from swapping the cranks?
