My Moki glows have done that too, you're better off letting them cool off before restarting. They don't like to start when they are already hot (fuel evaporates in cylinder or crankcase?). But I never usually have a problem since I rarely run back to back flights.

I couldn't say why Nogyro is having the problem he's got, but once I got the faulty ignition replaced the engine will start anytime you want to try it. My new ZDZ-100 is the same way, cold, hot or just warm it will still start...
I did have one ignition fail on me and DA replaced it NC. The engine still acted the same way when trying restarts 5 to 10 minutes after landing. If I was lucky enough to get it started, it sounded real lean for 15 to 30 seconds, then it would straighten up and sound normal. If you tried to set the low needle to compensate for it, then it was extremely rich in the air. Put a little fan in front of it, problem solved. I've got 30+ gallons though the engines, not a break in issue. Still think it's a heat/fuel vaporizing/ring cylinder fit issue....... Got a stock G62 I hand start cold or hot, never acts like this. I know of one other guy that has the same issues with hot starts........
