My motor starts ok, and runs well for a while. It will bog down sometimes, under high speed. It will die sometimes, too. Once it's warm, and it dies, it becomes hard to start, and keep running. Problems are intermittent.
Plugs look ok, about what I'd expect. Gap looks pretty big, though, about .050. Does anybody know the gap?
One note is that when I prime the fuel, the bulb never get's hard. I can pump it forever. Could that mean carb problems?
Check the spark when cold and when it dies. As for the primer not getting hard sounds like a kit is in order, float isn't working or something in the carb. The 2 could be related, start with a carb rebuild.
