UPDATE April 1st (No Fooling) Took photos of both the 1985 & 1986 Mikuni carburetors; looking the sameOh sameOh... They both have 3 HOLES plugged with what looks like two part epoxy... Not sure what the glue is meant to hold back or plug off: Gasoline, vacuum or close off the phenolic mixing body's casting vent holes..? Maybe I could use the same epoxy glue to fix the crack in my 1986 Mikuni (see carby2 photo)..?

Truck ran perfect today although still had a little rough running the first minute while choked BUT it's much less rough less duration & no black smoke or rich gas smell like before... Starts quicker too & has more umph to do 80MPH in an area previously limited to 60MPH by the truck's performance...

NO FOOLING HERE R PHOTOS:
