I have a RC10GT with a box starter setup can I convert it to a pull start?
pics or websites would help

Yes it would cost a good bit and the best way would be to get another engine as the parts would cost you just about as much.

Not really I have changed one just by adding a spacer to the engine mount (aluminum or composite is best) of about 1/4" so the pull start will clear the frame. and just bolt on the approporate starter/starting shaft for that engine. most have tham available. Just keep in mind depending on the motot you have to seal up the back plate when you install the starter shaft backplate. I use RTV non sillicone.

Cheers

my friend also is giving the stinger exaust to me which routes it to the back could i put a pull start in then?
