LATE TODAY did more disassembly & gasket clean off to MR. MIKUNI; top of the carb needs removal of dah choke breaker diaphragm 'n then should be ready for a hot bath in dah ultrasonic cleaner... It's also gonna need the crud scraped off the two coolant water nipples on the wax pellet & digging deep to remove carbon in the bowl vent passage... My glass jar of Techron is chuck full of tiny little parts, many with tiny "O" rings... Surprised me that the only tough part to remove was the screw holding in the pilot jet... I failed to photo taking the float measurement after removing the top cover gasket but noted it measured .820" which would keep the fuel level on the lower side of perfect (right?) FSM spec is .787" (20mm) +/- .003" (1mm) The needle rubber tip looks OK to my old eyes & it held vacuum pretty well BUT the vacuum needle did fall but very slowly... Testing the J/Y carb float when it comes off the truck should be interesting cause that carb floods somehow... I am very interested to see if it has the same white plastic float or a slighty larger black float like the one that came from Rock Auto... I happened to notice the Autozone gasket rebuild kit has instructions that take the float measurement in a different manner & the picture looks like the larger black style float... The needle/seat filter had only one little spec of dirt...

So I will be posting some photos of my mess, starting now:
