When turning corner she sometimes stalls out. Also, she bucks at about 15mph after turning corner when she doesn't stall out. any ideas on this would be helpful. Thank you john

I would suspect a float set too high.

Murphy, it is almost certain to be a fuel delivery issue. What was the last thing you did to the fuel system? Chances are that the problem is related, such as changing a fuel filter, installing a fuel pump, rebuilding the carburetor?

Allen I changed fuel filter, put a upgrade fuel connection from fuel line to fuel pump. The connection was done two weeks ago the filter after that. The filter when I installed from Joes , was small when I installed then the filter swelled up which I thought was normal? If it was filter why wouldn't it act up on straight away roads? Just thinking out loud. The carb was working fine before. The stall normally occurs on a right turn at about 12 to 15 MPH. Maybe it has to be like was mentioned the float? The previous gentlemen mentioned this?

Deuce you may be right but I got carb from Charlie in New York he was highly recommended the only thing I did on install was adjust idle. Thanks John

It could have been perfect when shipped from Charlie but if the package got thrown around, I could imagine that little tab that sets the level could have been moved. (ever see the movie Ace Ventura, Pet Detective?! Jim Carrey plays a fake UPS guy) Hope you get it figured out, the fact that turns make it happen makes me think the fuel level is too high in the bowl and sloshes over. Do you get some black smoke when it chugs and keeps running?

Don't remember seeing black smoke but will see if it occurs. I remembered one thing though, when I changed the fuel line from pump to carb, one end the tubing stuck out beyond ferrule too much should be 1/8 inch and I told myself to cut it back on another day. Should have done it right away, that might be another answer? Will let you guys know when I work on it again thanks to all, John

I would guess either the float level is too high or the float has a small pin hole in it and is slowly sinking. I assume the engine is stock or close to it and you are not running an electric pump.

Murphy, I suspect that your fuel level is too low. Your fuel filter may be restricting flow and starving the engine, or you may have a vacuum leak. Where is your filter located and what was the upgraded fuel connection?

Murphy, your having replaced components of the fuel system, then the problem developed... That is your clue to solving the problem. The fuel line will suck air at imperfect connections, and will reduce flow from restrictions. The fuel line upgrade and the filter could each contribute to the problem, which will lower the fuel level in the bowl. Don't be confused about the turning corners thing, as slosh in the bowl will send a false fuel level signal to the inlet valve. Regarding the upgrade fuel line, I suppose you installed a new flex line? Quality of flex lines varies greatly, and has been the cause of fuel restrictions for many others. One known good line is supplied by a man named Sherman? who advertises in the V8 Times. He offers two versions, one straight through and one with a check valve. My opinion is to forget about using a check velve.
