I have installed the engine and the Ross prsu on my plane but I am having
hard time finding a starter to fit the gearbox.

Does anyone here know what model starter will most likely fit my gearbox?
My is a 2:87 to 1 ratio, I believe.

I do appreciate any help.    Thanks

That is a good question. There are two popular Mazda rotary
starters that might fit. The 12 tooth and the 13 tooth.
The 12 tooth has the solenoid mounted on a 45 degree angle
and that is the most recent I suspect. The 13 tooth is
an earlier version and less common. The solenoid is mounted
on a 90 degree angle. The Ross looks like
it uses the earlier 13 tooth version. In any event you
should be able to mount either one with a bit of surgery
on the Ross bell housing. There are minor differences
in the mounting.

You might try calling Dave Atkins in Puyallup Wash.
He has tons of used rotary parts.

I've got a used mazda rotary starter, an older one I think,
it's yours if it will work and you pay the shipping.


I've gotten the airworthiness certificate for my RV-4,
now just getting myself back  up to speed to fly it.

Brian , I do appreciate your help.  If Ken Welter can find his, I could
check and see which one will fit better.  The one I won't use I will keep it
standby for someone that would need it in the future. Thanks
You can send it cod to:
