My previous source of Motorcraft 2100 jets seems to have dried up. I found some odd sizes at Green Sales. They are in Cincinnati OH.

No wonder they can be hard to order. The F*rd part numbers are crazy. I will edit in more part numbers if you PM me.


52F (per Number Dummy) CJ-133 / C3UZ-9533-A

54F (per Number Dummy) CJ-146 / C3GY-9533-C
55F
56F (per Number Dummy) CJ-147 / C3GY-9533-D
57F ................................. CJ-129 / C3OZ-9533-A
58F appears to be ...................... / C3GY-9533-A
59F appears to be ...........CJ-130 / C3OZ-9533-B Marked "Jet S5"
60F appears to be ...........CJ-145 / C3GY-9533-B Marked "Jet S5"
69F …................................CJ-150 / C3TZ-9533-B
70F....................................CJ-132 / C3TZ-9533-??

If anyone has a chart of part numbers, or can make sense of the code system, do post it.

Good advice:
"Decrease the jet size one number for approximately every 2000 feet increase in altitude. " "Increase one number for every 35* drop in temperature."

 

I used to have a chart, but have no idea where it went. Old hot rodders trick, take a pair of jets you don't need, drill them out and tap for Holley jets.

 

All State Carburetor and Fuel Injection has them in any size you want. They are sold in pairs only, so if 1 52 jet is ordered, two will arrive.
