still more idle problems...damn

ok, so now i have replaced the distributor cap and rotor, i noticed that one of my coil wires were fried, replaced coil. and i also replaced the distrubutor modual that is inside the distributor. and now i the idle is even worse, i'm afraid to drive it. I'll try my carb tonight...

i tried to tell you

i think it is the idle tubes in the carb.

if it was spark, it would miss at all rpm's. not idleing is fuel in my opinion. try the idle tubes- it's easy and FREE. you might be one happy dude if you get it fixed and it will run great like it used to.

In addition, look for vacuum leaks. Normally, a vacuum leak causes the idle to go up and give you a lean miss. Start with the basics and try to avoid the shotgun approach. Based on what you are saying, I have to agree with Sas...if you carefully look down the carb, if the tubes are blocked, you will see gas droping down onto the throttle plate. This is a quick check and fix.

You can tell if your bad idle is air fuel mixture by putting your hand gently over the intake to the carb and start to cut off the air supply. If idle gets better, then your running real lean. Are you getting black smoke out the exhaust? If so, then your rich. It's not uncommon for the float level to change. Pull the top of the carb off and look at the gas level. The top of the float should be parallel to the surface of the gas and the gas level should be at least 1/4" from the edge of the bowl.

Let us know what you find.

That looks like my Carb right before I gave it back to the NAPA guys in exchange for a MC2100..

MC2100 is the only way to go.
