Hi, having carb trouble. 2 questions for the group:
1) What is the proper spacing/gasket set up for the carb base? I have a plastic spacer about 1 inch thick, a tin plate shaped like the gasket and 2 paper gaskets. Shouldnt there be 3 gaskets?
Im thinking: paper/plastic/paper/tin/paper. Am I correct?
The plastic is a heat spacer and I think the tin is too keep the exhaust from the crossover passage from contacting the carb directly.
2) Other than fuel psi or float problems (sunk, settings) is there anything that will cause an AFB to send to much fuel at idle?
I am finding the gaskets mentioned above to be wet when I remove the carb, and the engine is obviously running rich. (Very)
I made sure the vacuum pistons for the metering rods were free.
I see no traces of fuel leaking internally when I look in the carb bore. (running or off) Suggestions welcome
Thanks
Tim
Hi Tim,
Im not too good with carbs. I think theyre a little wacky, myself. Anyway, the order should be gasket, insulator(plastic thing), gasket, metal shim, then the carb. There should be only 2 gaskets there. And be sure to always have the metal shim there, or else the car wont idle.
As for your other concern, someone more experienced with carbs should tackle that one.
