I have a 1957 F-100 with the 223 I-6 motor and Holley single barrel carb. My question is

On the top of the float bowl there is a small opening that looks like a raised hole with two small openings on the side. Inside that hole there looks to be some type of plug.

Well my plug is no longer in that hole and it is pumping a steady stream of gas out of it. I looked at a bunch of rebuild kits but none of them look like they come with any type of plug for that.

What do I do? Is there a place to buy that plug or do I just make one with some epoxy? Any info or fixes will be greatly appreciated.

 

That is actually a vent. Shouldn't be plugged, needle may be stuck open or float not set correctly. When carb is adjusted correctly no fuel should pour out. I hope this helps.

I know I can't close it completely off but it used to have a cream colored plug in the top of the vent hole. I looked at about a dozen of them in pictures they all have that same plug in the hole, or at least in the top of the hole above the two small vent holes, on my carb this cream colored filler is missing, and the gas did not start leaking until that blew out...


Could this be the reason it's leaking gas from that hole or do u think that my problem is internal with a stuck float?

 

I haven't seen the top open, but I am fairly new to these myself. I have rebuilt 2 and haven't seen the side vents plugged up. I'm sure someone will be by with more knowledge than me to help you out. You can search 1904 in the straight six forum, or Mikes Carburetor Parts is a great source for info, always responds to emails as well.
