RB 928 rotostart conversion question

[pliebo]

Hey there, finally got my tm928 and put a rotostart conversion on it. the shaft that fits into the one way has a 12 mm hex on it. I rigged up a couple of sockets to fit it but there is nothing to hold this thing in. When the engine runs it just wiggles out, falls out and the engine dies. first of all will this harm the engine if this shaft falls out and B) how do you keep it from coming out? seems like there should be a plastic cover of some sort but rb doesn't make one that I can find. Any help would be apprecciated.

It will suck dirt and dust into it when the shaft falls out.I wouldn't run it like that..A pic of it would be nice..

I found a rotostart cover plate from a friends cen nemesis, it holds the shaft in place and works perfect. I don't know why rb doesn't make one but I guess they're a standard thing so you could use a tiger drive , or other.
