Flywheels from 20B and 13B Cosmo don't fit Tracy's redrive, and you

can not

replace them with other 13B flywheels. I have tried.

My 20B is equipped with a 2nd gen flywheel.   Fits just fine.  Maybe I don't
understand the problem.

Tracy  (finally got electricity back)

The problem is that I wanted to use the original starter. It straddles the
engine block and the bellhousing. So I could not use the 2nd gen flywheel.
The bellhousing gave me 3" "free" prop extension.

Did you also make a new longer input shaft for Tracy's PSRU Bulent?

Kelly, I made my bellhousing to redrive adapter plate from 1/2² aluminum
plate. There is a small flange about 1/8² where the plate meets the bell
housing. I also bushed down the bolt holes on the bellhousing with steel
sleeves to reduce the weight of the bolts. I would make the plate first and
than measure the distance from the mating surface with the gear box to the
engine block. This will give Tracy the difference between the standard shaft
and yours. Mine came about 3" longer.
