Roto Start for Axial

[Rat Now]

Hey guys, I have a Axial (gold heat sink) motor , don't know what size, in a savage x I bought used. Motor fired right off but broke the pull start when it fired. I want to put a roto start on it but can't find the right one. It has a shaft that sticks out the back of the nut that the starter mounts to. Any ideas?

Will one of these fit an Axial motor?

I've never seen a gold heat sink on an axial engine, but if it says it's for an axial.28, or .32 it should fit those engines just fine. Can you supply a pic so everyone can have a look see?

Well it may be a crappy yellow lime green color. No engine size anywhere. Numbers on the bottom are 604189A Has a black case. I'll try to get some pics.
Thanks "Rat"
