The distributor wound up being moved counter-clock-wise from its original spot, twisting the vacuum advance module to the firewall and away from the front bumper. The engine settles down and runs really, really smoothly at idle in one spot, but it pings like crazy when it's left there and gas is applied to make the car go. I have to keep it farther away from that sweet spot than the idling engine seems to want it. There is still some stumble and vibration at idle that I think should not be present. If the pistons are coked up with deposits, would this cause pinging, dis-allowing the distributor to be placed where it most "wants" to be when I'm under the hood and playing with it without a timing light? I have had the car on the freeway at speeds around 70-85 for 30-45 minutes, and can't imagine going faster than that with the steering and prop shaft/motor mount? vibration issues that I must address. I don't think it prudent to run the car up much more than that in this urban area. I do have a leadfoot. Should I expect to see the deposits burned off over time? Was it the little old lady or what that brought them on? How long do you think it might take for them to go away naturally assuming regualr exercise of the car? Opinions are just fine on that last one - you can't say for sure, but I'm still curious what you think. Carbon comes from poor combustion? Is there a magic goo that I can add to the fuel? Techron comes to mind, but maybe that's just the intake side of things? ===== Kenyon Wills 6o LeBaron - America's Most Carefully Built Car 73 LeBaron - Long Low & Luxurious San Lorenzo/SF Bay Area __________________________________________________ Do you Yahoo!?
