Jim and Led:

I told you in post #3 it was a $#@%VW engine - actually the two cylinder conversion on a 1500cc Beetle engine. 750cc, approx 40hp. HKS takes the credit for it. Or that's my understanding, anyway.

Seriously, Jim, what is the airplane? Is it a Raven, or are my eyes not attuned to the Giles planes?

Bill.
