Plugs #1,3 and 2,4 fouling

Hmmmm, happened twice, buit not all the time................

If it isn't constant, I am still thinking float issues........ Jest because I have had trouble EB's in the past..... Are the floats hitting the sides of the carb body? Seats and needles free and tight?

IDK

Thats a strange one....

You like my before and after pics eh? thats a 318 to a small port head 390, thing pulls like a SOBeeatch@!
