I have a 85 GSL that I finally have running again after sitting for almost 5yrs. I have replaced the plugs, wires, dist cap and rotor, drained tank, new thermostat, and had the carb rebuilt. I can't get the car to idle yet. I drove it tonight and had something interesting happen. I heard a gurgling sound and found it was coming from carb. The fuel was bubbling in the carb. Why would this happen??? I loosened the gas cap and a lot of pressure was built up. What could be causing this and no idle?

 

fuel lines probly backwards. do you have two, one from the filter to the carb, and one from the carb to the tank. wait, that's how my 87 is. my 83 is set up different. well, just a thought. i think they have a pressurized system or something, so maybe that's a possibility. just a guess.

 

most likely your lines are backwards. clogged fuel filter? should do to much harm like your saying but its a start. if the fuel isnt the issue then check tps, or vacum leaks

 

Stock fuel pump?

Stock fuel pump and gas lines are right. New fuel filter as well. Nikki carb. I unhooked fuel line from carb when this happened and fuel kept running out slowly.

 

Fuel tank venting. I'm not too clear on the system, but it exists. Search the 1st gen tech section and you should turn something up. To verify this, just leave the cap a little loose and see if it stops doing it.

 

It could be either your float levels are screwed up or the solenoid located between where the in and out hoses go isn't plugged in.

The floats should be easy to check if you have a check mirror you can get for a couple bucks at your local parts store. There is a check glass on the side facing the front of the car and one opposite that on the carburetor. Removing the air horn makes checking a lot easier. The fuel should be visible and halfway on the glass. There is another on the other side of the carb as well.

The solenoid keeps the fuel from running in when you shut off the car so if it's burnt out or it isn't plugged in that could also cause your problem.

 

Thanks! I will check those things and report back

 

had this same problem, sold the car before i figured it out

 

Float levels are way low...guess the rebuild wasn't done right. He said the carb was trashy and he didn't know if it would work. The solenoid wasn't plugged in either....man, have I got carb issues....

 

Be careful. Low fuel level in the bowls could be due to a faulty fuel pump, or the fuel leaking out after shutdown due to the solenoid not being plugged in. Eliminate every other possibility before you tamper with your floats, because if you are wrong then you DO NOT want to open that can of worms.
