If it's the OEM carb, it's pretty easy to rebuild.

My '64 originally had G78-15 bias ply tires, which translates to about 215-75-R15. I think you could go up to 235 without looking too far off-stock.

For the carb, it would help to know which carb you have. If you have a 4-cylinder engine, you probably have a Carter YF, which is pretty easy to rebuild.

The V6 uses a Rochester 2G 2 bbl. carb,
As posted above, it's pretty easy to work on.
If you get it set up right they work well.

It could be timing related or just need a good basic tune-up. I'd start with points, condenser, plugs, distributor cap, rotor and plug wires...all very basic stuff. Set the timing and see what happens. If it continues, it may need a new timing chain and gears, very common to need this on the V-6, if it's never been done.

i most likely need all that done anyway. I think it is the carb though becasue after driving it around the block last night it went back to dieing when i step on the gas. If i spray carb cleaner in the carb it runs fine for a couple days then goes back to doing the same thing

Depending on your definition of "get on it", it could be the accelerator pump. If you slowly open the throttle, does it run OK? That is, does the dying only happen when you open the throttle suddenly?

Look down the throat of the carb and see if you can see a little squirt of fuel when you open the throttle. If not, the accelerator pump isn't working right. However, if this is the problem, I can't account for the carb cleaner fixing it for a few days . . .

If you have a manual choke, you might try pulling a little choke when you step on it. Not as a normal operating procedure, but as a further troubleshooting technique.

It does sound like you need to rebuild the carb.

You could also have partially clogged jets causing a lean condition leading to sputtering and backfiring. First step should be a carb rebuild. If cleaner improved it that's a sign you've got a debris problem. Good luck!

Rebuild it since if it needs cleaned out the internal seals (like the accelerator pump) are sure to be rotted or torn. With cleaning you always have a question. With rebuild you know.

That is a simple carb, barely more complicated than a lawnmower carb. Lay it out somewhere clean on a sheet of newspaper and tear it down.

good luck
