carb rebuild problems
So I rebuilt my motorcraft 2100 carb for the 302 in my 86 f250 and we have a problem.
I was trying to start it and did manage to get it somewhat running. However it died shortly after I let the gas peddle up. I went to take a look and see if I would see anything wrong with the carb and it looked like gas was running out of the top of the carburetor. I could not see exactly where it was coming from however you could see it dripping off the top tword the rear. I dont think I left anything out. I went back and checked the rebuild kit to see if i missed a seal or something and dont see anthing. Could I have something out of adjustment or something. I tried to set it up per the instructions however they were pretty vague. Even if I am off slightly I dont think im that far off.
any ideas

Well I thought about that however I think I followed the instructions pretty close. I used the little square and measured the float height as it stated.
Maybe ill try lowering it a little when I get home and see what that does

Its really easy to get the float level incorrect. You must follow the directions explicitly for your specific carburetor. You could also have a bad float. If it has a small hole in it it will take in fuel and cause your level to be off. I always replace the float on a rebuild. They're pretty inexpensive. Make sure that it moves freely, too. If it binds it may not cut off the flow into the bowl.

I know my float on my 2150 carb went bad, but since its made of foam, you wouldnt know it, and no matter how much I adjusted it, it would leak out the top. I would definitely replace it.

I found that at the measurement provided with my rebuild kit, the specs were a bit off, and with it measured at the spec'd dry setting, it would overflow. So, I did a little guessing and I got it right. Just play with it and adjust the TANG THAT TOUCHES THE ACTUAL NEEDLE, NOT THE METAL THAT ATTACHES TO THE FLOAT ITSELF! I cant tell you how many people bend the wrong part and it causes the float level to not change!
