mototr runs rich which rebuild kit
 

Ok I don’t want to sound stupid but how do I know what model Holley I have is it the 4150 or the 4160 the list numbers on the carb do me no good with the Holley web site I guess because the list number that’s on my carb for some reason is not a Holley number these are the list number I have two carbs list# 50265 and 50093 now these numbers are not on the Holley web page and the one ford number on the carb I cant’ seem to locate either E3ZE-9570-AUA,,so how do I know what rebuild kit I need??? or is ther a kit that covers all basic models

Ill take these numbers to work with me tomarrow and try to look you up a kit. We have carb listings on all the old Hollys going back into the early 60s.

E3ZE-9570-AUA is the ford part number. You should be able to take that number to the parts store and they can get you a kit for it.

The Holley 4150 has a metering block in the secondaries that takes jets that can be changed. The 4160 has a metering plate with a fixed oriface instead of jets that cannot be changed. The 4160 is the economy version but can be converted to the 4150 with a kit from Holley that replaces the plate with a metering block, thereby gaining the replaceable jets in the secondaries.

I took the list numbers to work today. The 50093 and the factory Ford number show a Tomco brand carb kit part# 5430 and float # 707 to fit that carb.
