Quote: Mr P,would that also cause a misfire at higher RPM??
the middle plug looks good.
I forgot to say that static is 8:1 on gasoline
Look at the strap on that plug,the line is just above threads,too much timing,but the inside of the plug looks good.I have to put a few passes on a set of 9's and see how they look.
I dont think thats true... since you have very little time on them the color on the strap is up on the flat but its hard to see being new plugs... your not fat based on those pics but you say cruise is... I've never played with that single bbl carb but if it tunes like any carb then you need to lean down the idle jets and fatten up the high speed to compensate for the less idle
