I recently purchased this truck and just looking at the carb, I'm sure it could use a rebuild and deep cleaning. It has a 'flat spot' when you start to pull away from a dead stop, sometimes it will stall, but as long as the engine has warmed up for a couple of minutes, just a slow steady push on the gas pedal and it's OK. Thinking the accelerator pump might be bad or going bad? I'm trying to ID the carb so I can get the correct rebuild kit. On the passenger side of the carb it says 'Made in USA Carter Warner for Motorcraft. Other than that, I can't see a model number on the carb. Is this a YF or YFA type carb? Any help is appreciated.

 

Hi! Could you possibly post a couple pictures of the carb? I'm sure someone here can tell you what is supposed to be on that motor for that year, but if it's not original - pictures would help a lot!

 

I will get some pics - it's on the engine now because I'm driving it daily & I don't want to take it off to take pics and bugger up the gasket.

 

No 240's after 1974.

There's also a video on there how to identify your carb. You shouldn't have to physically remove it to ID it.

 

That was exactly what I was looking for! I have a YFA carb. I'm going to get he numbers off the tag and the carb. itself and order a kit from Mikes Carburetor parts today.

Thank you a ton for this information! Great site here!!

 

Awesome! Glad it helped.

 

It sure did! Thanks again!

 

I rebuilt the carb last weekend and found that the ball bearing stop for the output of the accelerator pump wasn't in there! I soaked it for a couple of hours in parts cleaner, put the new pump in along with the ball stop and now it runs great! NO hesitation at all! Glad that's fixed.

 

Awesome! Always feels great when you fix something and the difference is totally noticeable!
Nice work.

 

100% improvement :-)
