First plug chop with PWK

Yeah. That was at least 4 sizes too rich. If you thought it ran good like that then you should be even happier with some 148s , 150s or whatever thins that ring out a bit and lightens it from chocolate color closer to a brown slightly darker than cardboard color. Believe it or not those last few jet sizes make a good increase in power on a dyno. Over 10hp.

How did it react to the 155? I would imagine it may even be happy at about 148-150. But don't jump all the way down at once.

Tried out 155 mains today and it was better for sure, but still way fat on the plug chop. Went to 150's and will try again after I get this lockup installed.
