I put new rubber gas line on my truck last week. My truck then started and idled OK but when I gave it more throttle it would bog out and not run good.
I had my carb apart yesterday. The guy who painted my truck 14 years ago worked on it. There was a speck of dirt in the Accelerator pump, the float didn't engage the valve correctly all the time, and we put the accelerator linkage in the middle hole. I put the carb back on yesterday and and it ran better when I accelerated. (This is in my garage, I haven't taken out on the road yet.) But it is still not running as it should.
My questions: what kind of carb is this (original to '54 F100)? Where can I buy a new one if needed? And, roughly, how much would one cost?
Pics of my carb:

There are a few places left with all of the parts and know-how to re-build carburetors.
I have had good luck with Davis Carburetor & Electric in East Rutherford, NJ.
That looks like a holley 94. I believe they were on F1's and early F100's. They're available on ebay and the rebuild kits are all over the internet. (pic and interesting link below)
Abe, you should be able to get a kit at napa. If you've had a good backfire up through the carb, it can cause the power valve inside to leak fuel. Dennis
I believe the correct carb would have EBU on the fuel bowl. Could be some crud in the carb. When you say "give it more throttle", are you really putting your foot into it? If so, the accelerator pump may be giving up. Chances are it's rubber, and not standing up to new gas.
Go to Fordbarn and look up Ken ct. or Charlie ny. Either one will sell you a good kit with leather accelerator pump and correct power valve. Be wary of some parts store kits, as they may have Chinese rubber accelerator pumps. Even if they are leather, the power valves will be wrong.
Thanks for all the help. The carb was rebuilt by my Bro-in-law this winter. And it was NAPA where I got the rebuild kit. The link to the Holley Carb page was interesting. And Ross, the link to the manual for Holley carbs is useful. Thanks.
The accelerator pump is rubber so that may be a problem.
When I started this thread I was frustrated and wanted to know if I had to could I buy another carb it this one couldn't be fixed.
I think I have narrowed down my carb problem. I think the shaft for the butterflies is loose. I have a catalog where I can order an oversize shaft and have found a 75 year old man that has a machine shop that works on carbs. He can bore out the shaft hole and make bushings, etc.
Obviously this would suck air and mess up the air/fuel mix and thus make the problems I have explained earlier when accelerating. He asked if it starts hard and it does. He said that is a sign of this air/gas problem.
Leakage at the shafts only affects idle to a noticeable degree. Even at that it mostly affects the seating of the butterflies, getting a reliable idle speed.
Check to see if there is a good squirt coming out of both accelerator pump nozzles. The "good" pistons for the accel pump are now usually blue, indicating good for modern fuels. To be honest, I haven't seen a black piston in almost 10 years, sounds like maybe an old kit. You'd be able to see deterioration if you open it up.
And remember, 90% of carb problems are ignition problems...
