Carb Recommendation Please!
I recently purchased an 84 F150/5.0/2150 carb/auto with 84,000 miles. The PO sprayed it down with oil every fall, it doesn’t have a bit of rust! It didn’t do the paint any favors though…
It had carburetor issues, during the rebuild I saw what could have been a crack but hoped it was just discoloration. Back on it would start with difficulty but ran horribly. Turns out gas is spitting out of one of the bowl vents. I double checked float level etc., and I can’t see any reason for it other than a crack.
What should I replace it with? A 2150, or something else like a Holley? This is a get it running project (for now), so whatever I get needs to directly replace the 2150, no new intake.
Can I eliminate the EGR plate and maybe the spacer plate and bolt it directly to the intake? I believe I’d have to rejet to compensate for no EGR.
The maze of vacuum lines and possibility for leaks in the mostly original colored plastic lines is ridiculous, I’m used to pre-70 stuff. The thought of a simple carb and a few vacuum lines is very appealing. I don’t think I have to worry about an emissions test.
Thanks for your thoughts!

I would keep the EGR plate, just block it off with a homemade block-off plate where the EGR bolts on You will find some things don't fit quite right when the carb is lowered onto the intake without the EGR plate. On the carb, I would keep trying with what you have since it fits. The most common reason for fuel spitting out of the vent is the fuel level is too high, and that is most commonly caused by dirt under the needle of the float. Make sure you have a new fuel filter. You may want to take the fuel filter off and dump it onto a clean white paper towel, and see how much rust is in it. If you have a lot of rust, you will continually have problems even with a new carb, till you get a new fuel tank.
These are very simple carbs, I would stick with it. Also make sure there is no fuel in the float, sometimes they can get a leak if they are brass, or get heavy if they are the black plastic type. If you are having trouble installing the little damper spring onto the float arm, just take it off for now, you can run without it. If you get it on wrong, it can cause problems also.

I generally check-out by the mid 70s when the primitive emissions junk was still primitive enough to be last minute add-on geegaws that were obvious enough to be spotted and easily eliminated. By the 80s this stuff was (literally) hard-wired into every function. I managed to get some late 70s models through emissions by the skin of my teeth, but now l'm (back) in an are that doesn't require it. Yet.
Best of luck w it... post some pictures. We love pictures.

You made a good point about fitment with a different carb, I will stick with the 2150. I have plenty of other things to handle, starting with those pesky vacuum lines!
Thanks Dave!
