Runs fine when opened up more though.... I've been searching the site for answers but I use my phone for web browsing and its not ideal... I replaced the bowl gasket because it was leaking the carb has never given my problems before so I didn't do a full rebuild that was two or three days ago cars been running great...
untill today when I was pulling onto a busy road the car died and then it ran really rough.
Car starts right up and idles real slow and rough out of the blue... I used the walker kit and my float was fine... I can drive it but I have to kinda punch it off a stop or it dies its a holley 1920 has a holley rebuilt sticker on it...
Its doing the same thing again only less extreme it still dies with light throttle... if i open it up its fine but if i crack it a littlest it starts to stumble and dies, its also fairly hot out here in SC and it seems to happen when hot...

Have you connected a vacuum gauge to it yet? If so, what are you reading?

Pick up a cheap one at harbor freight. Without a vac gauge, tach and timing light everything is just a guess.

Got the idle handled, however I'm gettin a intermittent puff sound accompanied by suction from my tailpipe... I also have a exhaust leak on my exhaust manifold... however its been like that since I bought it. Thanks for all the help and info from you all!

Ps planning to go to harbor freight this week, I need feeler gauges as well.. anything else I need to pick up besides vac gauge timing light?

Suction in the tailpipe could indicate an exhaust valve problem, sticking perhaps.

Recommend considering a cylinder compression test gauge, in addidtion to the other stuff.

In my experience, a chuff or pfft from the exhaust pipe is a burned valve. The only thing I've run across that was similar was a sticking hydraulic lifter.

Do that first. Sounds like a tight exhaust valve.

im getting the chuff from the tailpipe (though not as bad as before) and a lope and a lot of vibration...

it dies under light throttle and the less i open it the faster it dies...
