Some excellent stuff in this thread - thanks guys. My experience with mags is that they either work or don't, so if you have some spark you are probably OK there. A simple hold-in (rubber seal) comp gauge should give you a ballpark reading on compression. If that is decent, and if you are getting fuel squirting into the cyl with each pull, I have to go with the fellows who think that the bottom end is flooded. There are some devils in 2-strokes, and this is one for me. The 2-stroke Polaris ATVs here have a drain plug in the crankcase bottom. When needed, I remove the plug (yes, stuff runs/drips out), crank the engine for a short time with NO FUEL INPUT, and let it sit open for 24 hours. Then, plug in, fuel on, maybe small touch of ether, and it rolls. Hope this helps.
