the engine did best on a 16-6 apc. Just break it in on that and leave it.. the props they recomind are to big. I also took a head gasket out, and it seemed to like that better (more compresion) it had 2 gaskets? And used a perry pump. Iv had about 4 gallons on this in a cmp super chipmunk and I think the engine is great. just take your time breaking it in via OS style since gms dosnt give you much of a breakin.
ya i went to powermaster rite after that run. have about 7 gallons threw it now on my super chipmunk. Havnt had a prob. very happy with GMS for the price.
What percentage nitro are you using? I have heard that they like a low percent.
thx
