flooding
The last couple of times I cranked my '76 F-250 (360) it has ran well until it warmed a little, then it begins to flood and i have to keep the rpms up manuallly. Now I have a Holley carb. that has ran well on other engines, it has been sitting in my shop for a couple months. i'm thinking i don't have the idle mixture right, what do you guys think?

No, it is a manual choke and it is dis-connected. I checked it today and it is wide open, just like I left it. An open choke would be a problem when the engine is cold and my problem is when the engine warms up. When it's cold it runs great. The only other thing I can think of is to play around with the mixture screws some.

I changed the idle mixture today and it is now idling good. I started with the screws all the way in and then turned them out one turn. It would run but not idle. From there, I backed the screws out 1/2 turn at the time until I got it to idle decently. Thanks for the help.

You will need to hook that choke to somehting to keep it from closing. I used to work with a guy who had a sweet old '57 F-100. It had a 351 cobra jet in it and it would move. He put on a new carb and threw it on there drove it a bit and got it tuned real good. He took off, with me following, around a corner. He got on it big time. Started to get side ways, and then it died. He had enbough momentum to get in a parking lot. I pulled up and asked him what happened. He told me what happened. He is really pissed now. we spent most of the day working on it. He then gets in the truck I was driving, and pulls up in front of the truck he was driving as if to pull it home. well while he is figuring out how to hook up the tow rope I get the truck running again. He asked me what did you do? I told him that the choke slammed shut when he hammered it and that was all that was wrong. Got back to his house hooked the choke up and went out to find some prey. Boy was that a fun night.

I ran this carb for a long time on another truck and had no problem with the choke going closed but I have had that problem on other carbs. Thanks for the input.
