Do one thing at a time to see what happens, other wise you will be guessing what the problem really was

Yes, I second the methodical approach.

I'm curious about the resistor sparkplug caps. The Yamaha data I researched and posted called out for the B8HS-10 plugs. Rodbolt said it was OK to run a resistor plug if it didn't call for one but said not to run a non resistor if the manual did require it.

I assumed (here I go again) that the resistor caps had the resistance built in for the radio noise and also to stabilize the spark.

Quote: I do have 19" propeller on the forth motor. It's been a month since I put plugs in that motor.

How about seeing if the lucky prop brings luck to a different motor and miss fortune to the month long runner...
