I have a 48 Fleetline, but it has a 235 in it. Recently I couldn't get it to start, so in troubleshooting it I found no fuel was being delivered to the Carb. I replaced the fuel pump and now I'm getting fuel to the carb. However it won't start. I put a little gas down the Carb and it started right up for a second so I assume its getting spark. I'm thinking I have a Carb problem. How can I diagnose it or should I just have my Carb rebuilt?
Thanks
Jason

Most likely you have a stuck needle valve. If you are sure you are getting fuel to the carb, strike the carb with a screwdriver handle. If this don't solve the problem, remove the fuel line at the carb and use some low pressure air into the fitting to the carb. You can also improve the situation by spraying some, carb cleaner, WD-40, or starter fluid into the carb fitting. Once you get some flow into the carb it will automatically clean the needle seat and prevent further problems unless it sits for a long period of time. Don't send the carb for repair until you have given it a fair chance.

Thanks for the help! I'll try your suggestions next. I took the fuel line off at the carb and cranked the engine, and fuel came out of the fuel line (I wanted to make sure the new fuel pump was working), so I know gas is getting there. I hate to rebuild the carb if it doesn't need it.

Ray has given you good advice. I, too, think the problem is a stuck needle valve. The only thing I would change from his suggestion is rather than strike it with the handle of a screwdriver, I would recommend the flush side of a small ball peen hammer. Go up in size until it cranks. (Just don't bust the casting.) After all, you have to get the critter's attention. Sort of like a stubborn mule. Charlie  BTW: The stuck needle can be blamed on ethanol. It gets the blame for everything else. (I'm just trying to wake up Solon. We haven't heard from him lately.)

Charlie, I agree with Solon. Ethanol should NEVER have been added to gasoline! The blending of the two produces crap!!!!

You didn't mention if the car had been sitting for a while...But, it does sound as if it is just a stuck needle...As I've mentioned before ( your probably tired of the story ) about how I used a rock from the side of the road to un-stick the needle...In my case it was stuck open, though...It was flooding the engine at low speeds...

Thanks for the help everyone, tapping the carburetor worked! I tapped it, tried to start it, tapped it some more, and the it started right up. Thanks for saving me a carb rebuild.

If some of us hadn't had that problem in the past we would not have been able to suggest the tapping. I recommend the handle of a screwdriver as it is harder to hit the fuel inlet hard enough to break something. With a few raps it typically is enough to break the bond between the needle and seat.

"Deathanol" is absoutely pure crap! The only reason that Charlie likes "Deathanol" is because he apparently drinks the stuff......as you can tell from the nature of some of his postings. Mercy!!
