Ever try to fix something that isn't broke?
I was cutting with the 029 (64cc) noodling up some rounds. The engine decided it didn't want to rev over about 7,000 rpm. I pulled it out of the wood and revved it, same thing, 7,000 limiter, no misfiring or four-stroking, just loss of power. Finished cutting the wood using 7,000 rpm.
Checked the tank vent and fuel filter, worked fine. OK, probably the plug or coil. Plug looks great as does the fuel mixture. Figure if I rev it with a different plug while the coil was still cold, I might be able to diagnose if it was the coil. Fire it up and rev it, it still has the 7,000 limiter. I continue to hold the trigger for about another 10 seconds and it starts to clear, fades back again and then BINGO goes to max revs. Revved it a few more times and it works perfectly. Put the old plug back in and it works perfect. - What the Hell was all that about??
I just know that damn Gremlin will come back the next time I'm cutting with the saw.
