Ford Script Carb. Acting Up...?
I'm running an old Ford script 2 brl. carb that has been running well until a couple of days ago. When off the gas its lopeing at idle and has cut off at lights. You can close the choke and it runs better, vaccume advance is working correctly, timing is right on, the interesting thing is it wants to run better with the jets turned WAY in (lean)...? I'm talking 1\2 a turn or less.
You open the jets up to 1-1\2 turn to try to adjust them and the lope get really bad but dissapears when you turn the jets back in real close. I think this is too lean and dont want to burn a valve. I dont know if I got a bad batch of gas or not(have filled again since this started.
Any Ideas?

Your carb probably has a bad power valve. These 94's are famous for blowing them out during backfire. Or maybe it could just be some dirt (doesn't) take much.
I would just get a kit and pull the carb and clean/rebuild it as necessary...slim

ditto what slim said . the 94 on my flatty gave me lots of headaches . this was one of it's favorite games , what you describe . kinda the reason why i bought the adaptor from speedway to go from the three bolt to a more modern 4 bolt carb i.e the rochester 2 jet that i'm gonna run on it . i dont have any luck as of the last few years with anything that even resembles a holley !!!!!!!!!!!!!!!!!

Thanks guys....I think I have another power valve to put on....already have rebuilt the carb recently.......will keep my eyes open for a 4-brl. intake for the old 239 and find a nice carb for it then.

Maybe it's just me, but I've had good luck ('bout time!) with the 94. I've got three vehicles running on one, I've finally learned to figger them out and I can actually rebuild em in a few minutes. The biggest problem with em is dirty gas, or as Mr. Moss said "dirt in the fuel line." I have learned to run a filter upstream from the fuel pump and change it often.
