Need help on carb ?'s please!!!

[brans72]

I am really trying to get this 1967 C10 short bed running for my wife but running into little bit of trouble. I was given the # F1208taj off my enigne and told it was from a 73-74 6-250 Chevy C 20&30 &K20 ,GMC ser C 25 &35 &K25. I need a single barrel Carb badly but not sure what year etc to buy! So can someone please lead me on the right track??? I am not sure if 67 had a manual choke or what on it. I know the broken carb on the truck has a big plastic dail on the front that says GM Rochester but it is broken on repair. I am ready to buy just need to know which model or correct info need to order it. Thanks Brandon

The stock carbs on the '67 trucks had manual chokes. The one on my truck is a from a '69 l6 250, it has an automatic choke operated by a coil in the manifold.

The carb I have has Monojet on the side of it.

I think the LMC catalog has some pictures of the different carbs.

But which carb would be better to use manual choke like the 67 came with or the like the monojet with something like a auto choke?

i perfer manual choke, it gets cold were i live in winter and the auto choke was opening to quick, i need to keep at 1/2-3/4 for almost two mins on my 292 sometimes in the winter, depends on what u want to do just turn the key or play with a knob and have fun starting it

The LMC catolog shows 67 as a carter with a manual choke and 68-71 as a rochester and did have a manual choke. They also make an electric choke conversion kits. Hope this helps

[willys72fleetside]

I do know that the earlier auto choke units were not as reliable as the manual ones, as long as the driver remembers to open the choke

[292farmer]

yes please remember to open the choke, i worked 24+hours straight shoveling snow one time forgot to open choke man that truck ran like crap bounced head off steering wheel when it died suddenly and ran hot enough to melt snow in a 10ft circle lol..

[brans72]

So which carb though? Carter,Rochester etc???? stil trying to figure out which one is better here. Thanks for help so far guys.

[brans72]

Who do you also recomm buying from? I know Rock Auto seems to have best price right now. Brandon

[willys72fleetside]

It doesn't matter who you buy from, these things are only rebuilt from a hand full manufacters. I like the rochester better, I feel the parts are more abundant.

I've bought single barrel carbs from O'Reilly's and Auto Zone in the past. It's easier to exchange if something is not right with them (which I've done).

You stated in the first post that this truck is for your wife. Will she be OK with a manual choke? You usually can't go wrong with either Carter or Rochester for a stock replacement. But I also agree that Rochesters are quite common. They are also very reliable. So that's my vote. If you can get an automatic choke, go for it. Less to worry about every morning when you (or wife) starts the truck half-asleep.

After talking to a company that rebuilds carbs for a living, the guy told me sounds like I have a car carb on the truck ( seems engine is not orginal). He recomms I mail him my carb and let the go through it fix a couple stripped bolts,rebuild,fix couple broken parts and do a bench/flow test (if you wanna call it that) and send it back for $200.00 but right now I am not sure what way to go here guys any help on maybe what I could/should do?
