High idle or just crazy?

[Matthew Goeke]

My opinion, the guy was trying to low ball you. If he couldn't figure out how to get the radiator cap off, didn't realize the car would idle fast when first started because it's supposed to, and was worried about a little smoke from the manifolds, oh and didn't even check the body or frame, he doesn't deserve the car anyways. When I go to check out a car, especially a G Body, I crawl under it and look for rust. Check the trunk, rockers, etc. The car should idle fast when first started till it warms up, especially in cold weather. Be patient, someone who knows what you've got will come along. Expect to have to deal with a LOT of idiots in the mean time though.

oh yea also he tried to start the car without hitting the gas at all! i stood there disappointed hoping he would figure it out.

Don't spray lube on the carb linkage. That will attract dirt and make it worse. If it's cruddy spray carb cleaner. Make sure it is clean and free to operate. After it gets good and hot take off the air cleaner and see if the choke flap is all the way open. If not- that's your problem.

I should have added the use a dry graphite lube....or a carb cleaner

Dude had never messed with these older cars probably. Didn't have a clue. I'm still amazed that he couldn't get the radiator cap off. What kind of moron can't figure that out?

You have HEI so it is not tricky at all. There is a terminal on the distributor cap just for a tach. It is right next to the pink ignition wire terminal. Your tach will use three wires. That one, a hot, and a ground. Easy peasy.

It should, but, you get what you pay for. Read the reviews. They haven't used points ignition in 40 years so all new tachs are made for electronic ignition. Mounting it will be a pain. I am liking the pillar gauge mounts more and more.

oh i was thinking about just hooking it up in the engine bay to test the rpms, im going to take it out when i figure out the idle. id like to keep this car as stock as possible.

I get it. Yeah, that would be fine. They used to sell small diagnostic tachs cheaply. All you would need is a spade connector to attach to the HEI, and alligator clips for power/ground.

ive looked into getting a tach, but never went through because it seemed tricky, do you know how to install a tach or where i can get one? also i want to thank everyone for some quick and good replies.

I just use a dwell meter with a tach mode when I set or check idle speeds. Once I am done I take it off, the dwell meter is also usefull for checking the CCC system.

Something like this may serve you better in the long run. Jared- Sorry- I didn't mean to step on your post. I didn't see your eBay link.
