    2 piece plate, stock cooling. I didn't really do a hot pull from WOT today but the plugs did look good when I got home.

    I know what you mean though. A quick pass and long run are completely different things.

    You probably know this but checking your plugs after idling back to your trailer means nothing. A little fat is always good

    Yeah I know. They were pretty fat on the other motor they were on too. Not a whole lot of difference between it and this one.

    So you opened up your 2 piece exhaust plate to match your modified exhaust dump

    Got 0.086 mains in all 6 in the WH-46s. I have 0.056 idle jets. The idle is definitely on the lean side. Im thinking of trying some 0.088 or 0.090 mains to see if i gain or lose power on top and go with 0.052 or 0.054 idle jets to richen up the low end a smidge. you reckon just a richer idle jet would increase the fuel across the whole range since the idle never stops flowing in WH carbs?
