RE: ASP Engine availability?
FWIW, the blue valve cover for a Mag 52 is , or was $6.95. It was the only part different in the parts list between the Grey and Blue versions.
Also FWIW, the Mag and ASP 1.20 is a really heavy engine. Compare the weight between the O.S and Saito 1.20 and it. The smaller engines though are on par with the O.S. engines.
