Well you got a newbie here and I am hoping you can help me out. I have a 1955 chevy second series truck, 235 all original. I have been having some problems lately with my engine. I just cannot get it to idle correctly. The other day my mother drove my truck and quite frankly she doesn't really know how the darn thing works. She leaves the choke out to far and fouls the plugs and leaves the ignition key turned to on ect. :rolleyes: However she needed to drive it becasue it was an emergency. Anyways the truck broke down on her, so I looked at the plugs completly fouled, caked in black. I changed them and still no avail the truck will not idle. So I thought it was the carb but I just had that rebuilt about a year ago.The carb is adjusted fine with the idle screw, but it still will not run. The thing is I can get it running yesterday with the pedal all to the ground and somewhat responsive but when I let off the gas it just dies. Whats the prob? :confused: Could it be that the points are fried too? If anyone has any idea please let me know! Also if you could give me some tips on how to tune up my baby it would be greatly appreciated! Thanks everyone
Sincerley,
I miss my baby. | | |

Does it have an inline fuel filter between the fuel pump and the carburetor? If not, install one. Sometimes a dirt-jammed float valve can be remedied by (GENTLY) tapping the carburetor housing near the fuel line inlet with a small hammer or a wrench, etc., to dislodge the dirt that's jamming the needle valve. If not, pull the top off the carb and carefully flush the needle valve area with carb cleaner. a good inline filter will trap the dirt before it reaches the needle valve, in most cases.

I already have a fule filter installed so I do not think that the carb is clogged. Also I have two carbs and I installed the older one yesterday still no difference. Is it the points then? I just do not know? | | |

If you change the points and condenser, change the cap and rotor. If it still doesn't run, advance the timimg. If that helps, time it for real with all the right tools and such. That was my problem and now I have a smooth runner.
Hope that helps

If it isn't a good blue spark, examine the points carefully. If they are burned they usually have a raised point and a matching pit burned into the faces. If you file the raised point down (carefully) you should be able to reset gap and make it run. If you are going to drive an old vehicle you need a dwell-tach. You should check the dwell regularly because it will change as the points wear. You can keep it running great by setting the dwell... gapping used points is not very reliable.

When plugs get extremely fouled, its hard to clean them well, and the spark jumps the carbon instead of the electrode. Try that before the points. And make sure you've got a ballast resistor or an internal resistor coil.

Several methods have been used by car mfgs over the years. The first was to use a coil and an external resistor. The others were to build the resistor into the coil, or to use resistance wire in the engine wiring harness from ign switch to coil.
But you can still burn up a set of points by leaving the key on with the points closed, or setting the point gap too narrow, or using the wrong condenser.
