Running too rich? Is there any way to fix this?
My 13b 88 N/A is pretty much stock, and I smell gas pretty strong. I am running a premix, and that may add to the smell, but it seems like it is burning rich. Is there any way to adjust this without buying a megasquirt or something similar?

AH, makes sense now..
Where could I find one of these and how does this thing work? I was thinking of just replacing my OEM o2 sensor, I am sure that would help!!

rich mixture on stock car, if you have your stock cats intact you might wana look into getting them replaced soon. Do you have a exhaust leak? if you have stock exhaust id imagine you would be seeing lots of rust since your located on the east coast.

You're not necessarily running rich. Make sure the charcoal canister is still good. It traps fuel vapors. Check the fuel pulsation dampener for leaks. Check for other fuel leaks. Of course, then you'd smell gas even before you start your car. The smell just wouldn't be as strong until after your engine bay gets warm.

Jumper the fuel pump check connector in the engine bay. Key to ON, engine off. The pump should pump and pressurize the fuel rails.
Wait a full fifteen minutes. Look for fuel dripping down under the car. Got fuel? Then fix the leak.
I like the charcoal canister idea also. NO charcoal canister means fuel vapors in the engine bay.
Also make sure the FPR vacuum line has vacuum when the engine is running. No vacuum would mean a touch richer at idle.
