Starts & restarts well and generally runs smooth, but engine starts to miss/stall after running wide-open for 5-10 minutes. Some possibilities that occurred to me:<br /><br />1. air leak in fuel line - but this seems unlikely, given the coughing/stalling doesn't start until roughly the same time, i.e. 5-10 mins of w.o.t.<br /><br />2. carburator gummed up - but I've run some "seafoam" through the carb and performance generally improved (better starts/restarts, smoother idle, etc.). I'm no mechanic, but I'm not sure what kind of carb issue (clogged jets, stuck float) would create this symptom anyway.<br /><br />The fact the symptom seems to occur consistently at the same time after a few minutes of operation leads me to think it's some kind of "overheating" issue - fuel pump?<br /><br />Any comments or other suggestions as to what might be causing the problem would be much appreciated.
