I am having trouble with my magnum 108 2stoke. it runs well for about 3 tanks then it start to fail (running hot)
every flight I have to adjust in idle and high. but it keeps on failing. I had used it for about 4 gallons. (first 2 gal. ran ok, then.....) I am usin 15%nitro and a masterscrew 14x8.
I have tried 5% nitro and 13x9 blade. eventually same thing( 2 emergency landings, 1 crash) changed plugs, cleaned inside out.
Heeelp ! before I discard this engine into the trashcan.
