Jet sizing

Ok, I can’t find the book that has all the list numbers in it. I assumed you have the 4054 list carb. I did see the 4781 which is geometrically the same carb and it had 80’s front and rear and 6.5 power valves front and rear.

For some reason I have 10.5 in the rear for that carb but I can’t verify that exactly.

Also remember that the emulsion stack, main air bleed and nozzle (booster) type and position relative to venturi all affect when the nozzle gets fuel.

They are interrelated. Other than the idle circuit, those carbs had a pretty good tune up in them.
