I don’t think that is the engine that won the 68 WC. John Tate and I use to go up to Washington DC On weekends and practice TR with JE Albretton. JE had borrowed that engine from Jehlic and converted it to glow and had mounted it his goodyear which placed 3rd. at the 70 or 71 Nat's. I don’t remember the engine looking like that . I think that is a later engine. I do know that JE’s up line broke and the engine went in and bent the crank. JE cut the end off and drilled and taped a new threaded rod to hold the prop before he placed at the Nat's
All that is from memory it could have been the earlier 67 engine
