194 Is Running Bad

Lately Ive been trying to get my 64 on the road. I recently put a rebuilt carb on it and it seems to be running better but thats not saying much. Whenever you take off from a stop it runs really rough, but once you get the rpms up it gets better. Then once you shift to second and the rpms go back down, it does the same thing. Could it be the carb? The altiitude is pretty high here, maybe I need to have it re-jetted? I dont know, thats why im asking you guys. Your imput on this would be great. Thanks,

Ryan,
Make sure your timing is correct then adjust your carb. Also make sure your vacume advance is hooked up and working.

When Donivan see's this thread he will most likely write a book for you...

When I bought the van, two cylinders werent fireing. We replaced the cap, plugs, and plug wires and that helped fire the other two cylinders. Now that its running bad, I think im going to have to replace the points. Ill let you know how it goes. Thanks for the help,

Ok so the compression and timing is good but whenever I take off from a stop it feels like theres not enough gas getting to the carb. I also have one of those clear fuel filters and there is no gas in it until the rpms go up. Could this be the fuel pump?

I know that the gas tank was cleaned out in 2007. I let the van idle for a while, then shut it off. I could see no gas in the throat. Where is the accelerator pump? I couldnt see any gas squirt into the carb. And ya, its a Carter YF.

Have you checked ALL the fuel lines.......at the tank and pump/engine? Sounds like its sucking air like donivan said. If the fuel lines are ok you may have a pinhole in the fuel pump membrane or the pump may be junk. Check the lines then do a preasure check on the pump.

Ok gas is sparying out of that nozzle, and there is no gas laying in the carb throat when I shut it off.
