I have a 74 F250 with a 360 and a type F-2 carb. My issue is fuel spewing out of the vent tubes on the float chamber. I have put a new float, shut off needle and valve, polished up the brass rod the float mounts to, new accelerator pump, I've done everything I can think of to address a sticking float but that doesn't seem to be the issue. Advice would be appreciated

 

Is this something that just started? Have you made any other recent changes that could be related, like add a electric fuel pump? Did you check the power valve in the front bottom of carb? If there is evidence of gas in the cover it’s probably bad

 

thats not good man
