My LG4 has the stock computer carb. It's fine as long as I accelerate moderately, but if I keep the peddle floored through a couple of shifts, the idle bogs down badly (sometimes dies). If I pop the hood after it dies, there is gas dripping/streaming out of the passenger side of the carburetor, right where the choke meets the carb. Is it flooding when I floor it? Why is the gas leaking out like that? Autozone says a replacement carb is minimum $289. Please someone help me with a cheaper fix! I don't know how good I would be with a rebuild kit, opening things that have tiny springs inside scares me. I don't even like tackling drum brakes anymore. I am pretty handy with a wrench, though. Anybody else think this is a fire hazard?

 

You might consider replacing the fuel pump first. It might be overpressurizing the carb needle/seat at higher RPMs.

I wouldn't say it's easier than removing and replacing the carb, but it is cheaper.

I suppose it isn't a fire hazard (yet) if you keep your foot out of it.

 

Now tell me if this isn't right, but aren't there two fuel pumps on this thing? The old mechanical, plus an electric close to the tank? Which should I replace first?

 

86's didn't come with the in-tank electric from the factory. If it has one, it was added by a dealer later as part of an "anti-vaporlock kit".

The mechanical pump has a return line. There is a relief valve built into the pump that sends excess fuel back to the tank via the return line. That's what controls pressure, so I'd replace the mechanical pump first if the car has both.
