I had the Magnum/ASP 108 on a GP Escapade 60 and it was running great until I lost all control and put it in the grond like a lawn dart. The plane was a total loss but the Magnum/ASP 108 looked like it was OK, just dirt in everyplace it could get into. I took the Magnum/ASP 108 home and into the shop and started cleaning it. I completely took it apart. I then put it back together and read this page about setting up the carb. I followed these instructions that you guys gave and the engine started right up. I am using Omega 10% full with a MAS Simintar 15x6 prop. I also have a evolution glow plug. I am getting over 11000RPM on a test stand and I think the engine is runnig better now then it was before. Thanks guys
