I recently picked up an 82 F600 car hauler, The kid did not know exactly what the motor is but I believe it like a 370 truck motor. The carb on it was an edeljunk and I tried a C1TE carb I had that I tried on my 55 272 and it ran super strong but limited it to 3800rpm and burned rich at Idle.
Its been awhile and I am kind of confused as to how exactly the carb works. The adjustment screws are in the rear metering block instead of the front and I think they work by letting more air into the mix instead of gas, you can hear more air going through the air bleads when you open them, if I close them all the way the truck idles fine but with no air when you give it gas nothing happens, the more I open them the rougher the idle but it takes the gas normal. The carb appears to burn somewhat rich which I don't understand because it came off a 292 C1TE truck motor that I have with the steel crank and now on a 370.
2.) There are 2 fittings on the carb, one just goes to the air filter chamber, probably for PCV. the other goes to the primary vacuum diaphram to hold the butterflies closed if remember correctly.
does anybody have any Idea exactly how these carbs are supposed to work, where I shold plum the vacuums etc.
Thanks in advance for any info.
