Dick Griswald in Arizona has one. He purchased it in Europe last year at the European SAM Champs. He says it runs great. The compression lever raises and lowers the crankshaft to vary the compression, I talked to Dick about it at the Eloy SAM contest in January 2006. Dick says he will bring it to the 2006 Muncie SAM Champs in September. This I got to see. I think he said he got it in the Czech Republic. Jack
