    Push the brakes and the hazards light up (solid)

    Check the simple things first. I had a S-10 do that to me once and it was the light bulb. The brake light filament had burnt up, broke loose from one side and crossed over to the parking light filament. When I would hit my brakes, all my running lights would light up.

    I still have dual points on my Honda CB750s. 4 cylinders, 4 carbs, two sets of points. Dial them all in once a year and they are screamers.

    Help with troubleshooting C20 350 that dies after short drive

    Okay everyone, it was dry here this morning and I got a chance to check out the truck with a fresh outlook. I kept thinking fuel, because it was acting like it ran out of gas and had spark after it died. I disconnected the rubber line into the fuel pump and dropped a line into a one gallon can...

    The weather forecast here was wrong today. It was freezing rain all morning and raining all afternoon. I hope that I can get out to the truck tomorrow and look things over. Perhaps walking away from it for a little while will give me a new perspective. The battery is on the tender and maybe...

    GMC Jimmy: the timing is set at at 8 degrees BTDC and the cranking sounds normal. I will hook up a vacuum gauge today and let you know. Just to let everyone know, this is my dad's old truck that was sitting in his barn for the last 20 years. No restoration here. Just trying to get it safely...

    Help with troubleshooting C20 350 that dies after short drive

    Roundhouse: I just checked. The accelerator pump does spray after it shuts off. Right now, the truck isn't running long enough to drive (< a couple of minutes). If I pull down my driveway, I go downhill. The rubber fuel lines were both replaced this month when I put the new tank in. GMC...

    Help with troubleshooting C20 350 that dies after short drive

    I should note that the pressure was measured with a harbor freight fuel pump and vacuum gauge. All I did was press the tip of the gauge tightly into the end of the metal line where it goes into the filter on the carb. Then my wife cranked it over until the gauge didn't climb anymore. I don't...

    Help with troubleshooting C20 350 that dies after short drive

    The choke flap is opening like after it is warm. It does open up relatively quickly. By that I mean, the upper radiator hose has not opened yet and the choke is all the way open. I have checked the plug on the number one cylinder after it died and it did not seem like it did not have the smell...

    Help with troubleshooting C20 350 that dies after short drive

    Thanks for the advice everyone. Here is what I have tried so far. I took the air horn off and the float was supposed to be set at 11/32" and if it was off, it wasn't off by much, I got it set to where it was perfect before reinstalling. Same result.... I moved my attention to the fuel pump...

    Help with troubleshooting C20 350 that dies after short drive

    I don't believe that to be the case. The fuel system was brand new before the rebuilt carb was installed. I just checked the fuel filter and it looked clean. I am having problems wrapping my head around the fact that the issue briefly "cures itself" after sitting for a couple of minutes.

    Help with troubleshooting C20 350 that dies after short drive

    I am in the process of getting my truck running after it sat for 20 years. I am at a loss and need some help. The truck was running fine two weeks ago...now this. The truck will fire up quickly and idle all day long (20 minutes fine) when I go to drive it, it runs for about four or five...

    Getting started on dad's old c20

    Thanks everyone. It has been fun going through this truck up to this point. Penetrating oil and wire wheel on the die grinder have been my best friends for the last month. I really like the wording of "as I remember it build". I am going to look into finding a Delco 2700. Thanks for that...

    Getting started on dad's old c20

    Hello everyone, Over Christmas, I was able to haul my dad's truck home to get it back up and running. It had been sitting since '97 and I was not brave enough to attempt to drive it four and half hours home to Richmond, VA. Here is what I have done to it since Christmas: -cleaned off 20 years...
