My tach is also off by a couple hundred RPM at 3k or so. Definitely less so at idle. No resistor in wire, new wiring harness was installed in the car that was built for HEI, so full 12v.

Definitely not just the tach. Confirmed it by physically moving the secondary shaft. Everything else coincides with the RPM increase.

I've confirmed that the secondary butterfly is sticking. Reached under the air cleaner and manually pushed the lever for the secondary butterflies, and the idle dropped. So do I need a new gasket for...

I'd ask him; tell him what it is. If I were a builder I'd be pretty stoked to be able to input exactly what I want for a curve in, rather than dealing with weights and vacuum stuff. Plus I'd get to...

I did my entire interior with stuff from Legendary. Great stuff, seat covers and door panels were spot on. Bright blue so took 8 months, that was over a year ago though. The lighting in my garage...

Nearly ten grand just in wheels and carburetor. Looks to be in really nice survivor condition, shame the engine rebuilder didn't find the right color paint!

I’ll check it out, thanks!



Mounts were new less than 1000 miles ago, I sure don’t see the shaker moving around much. “In gear” doesn’t rally apply, it’s a manual car.

Hanging idle

I've gone around and around with this, and cannot find what is causing my hanging idle.

I just replaced the distributor, so it's not that.

You're right about the idle. For some reason I had it in my head that it should be around 650, but that is low. It will idle there all day long without loading up. Part of the reason I've had it...
