RE: Combo pull and spin start
**WARNING**
If you buy the spin/roto start system IT WILL NOT FIT!!!!
Only the engines that came with the system from the beginning will fit the spin/roto start system. So if you have a Mach.26 or M.26SS or M427 They WILL NOT fit unless you buy a new back plate and one way bearing.... IF you Have already have a truck that came with it (raminator) you will not have this problem
