Default Magnum Four Stroke problems
brushfire2001,

w8ye is right. Probably has nothing to do with the loading up at idle problem, but with a 13X6 the engine is over propped! You can get away with an APC 12X7 if you have a really clean and fairly light plane, otherwise an APC 12X6 is the right prop.

OS "F" is the best plug I've used on all my Mag 4 strokes.
