os 30vg bumpstart to rotostart
 

I picked one of these up that is just bump start and I am going to put it on a monster truck so I want to put a rotostart backplate on it. What all will I need to convert it?

There were three versions of that engine.

If you ordered the regular bump start version, you might be out of luck, because then you'd need the crank too.

There is the exploded view for all three in the manual (with part #'s): http://manuals.hobbico.com/osm/30vgp...gpx-manual.pdf
