Fuel starvation a carb FIX
Posted 27 November 2006 - 06:34 PM
Here is what I did and it fixed the problem. I hope this explanation makes sense
I got 2 gas shut off valves.
One went on the top of the fuel filter hose that goes back to the tank.
One went on the gas line that returns gas after the carb float valve fills up
I pretty much closed them almost all the way and now the GL runs fine, all the time. I figure that the gas has to go into the float chamber now due to the increased pressure and the lack of an escape route to the tank.
What does everyone think of this? SC

I did start smelling gas last night and opened up othe carb return valve a little to relieve the pressure some. the pump got quieter , I guess due to it has to push gas less hard. I'll be sure to post if I blow up. S/C
I get like 27 mpg in the city and I usually RPM to 3000 between shifts. I figure its running OK and I got the idle on like 1ooo. (I should lower that some) The best I ever got was like 32mpg doing HWY in the 90's

Oh, does my 84 GL have a computer somewhere? I have not found it if it does? I do have a ECU light that comes on after about 15 minutes that maybe from a CPU. SC

I have used a 5-7 lb successfully that was big enough volume to power a v8. The old ea82 took it all flawlessly.
2 inch exhaust was a must have- I blew apart the oem setup annually (for 7 years annually! before I figured out what 2 inch saved), just when I thought it was sealed- kaboom!. There goes yet another dainty "lifetime" oem muffler...
If you try the pump would love to know what it did for you.
