Problems with LG4 4bbl

So, more recenlty, ive been noticing my car having some problems once its warmed up. I think it has to do with my carb, more specifically my choke, but heres whats wrong.

Once my car gets warmed up, it will lose a drastic amount of power. So much infact, that when i try to give it some guts and go, it will almost studder, no matter how much gas i give it, it will just want to die.

Not sure if its related, but the other day (very hot day), i was sitting at the drive through for a little while, and when tried to leave, gave it some gas, and it just died. Smelled alot of gas. So this more so confirms my thought of my carb flooding out, and it needing to be rebuilt/replaced.


As for that, the local places are charging about 250-350 for rebuilding a carb. I've priced a few from edelbrock, and their about the same, why not jsut get a whole new piece?

Any recommendations on a new carb? something that will mostly bolt right up.

Re: Problems with LG4 4bbl

Check your choke. Make sure the single wire connector is connected at the choke coil and that the choke blades are wide open (90 degrees straight up) when it is warm.

If you want to rebuild the carb you have we can help. Swapping to a different carb will require also changing the distributor (it's also computer controlled).
