For the nitro guys, problems with clutch bell, engine too far forward?

[Krawlin]

I have a Mugen MBX5-T with a Picco P3-28, and I am having some gear mesh, or better said "clutch bell position" issues. I can get the gear mesh set properly, however the spur/clutch bell teeth mating position is off. Basically, the engine sits too far forward, and the spur gear has a couple millimeters of the teeth not contacting the clutch bell, and the spur is very close to the bell itself. I am using a BCE chassis, and I dremel'd it a bit to move the motor mount back some, but it hardly helped. I also have to clutch bell shimmed as close to the flywheel as it can be without rubbing the flywheel pins. Anyway, the biggest problem about this is that it's starting to mess up the teeth on the clutch bell and spur gear. I cant seem to find a clutch bell that has the teeth machined right against the bell, which I think would almost solve my problem. Do Picco's just have a long crank and I would be better off to switch engines? Has anyone else had this problem? How did you fix it? And does anyone know of a company that makes an adjustable motor mount (allowing the engine to slide forward or backward) for the MBX5-T, or a motor mount that is adjustable from another vehicle that uses the same hole pattern that the chassis has? (I tried my OFNA ones and they don't work)

Anyway, thanks for any suggestions or help!
