Thought I had my 71 Cuda all ready to drive to the Nationals but..... car all of a sudden won't idle when I tried to go to work in it this morning. I just put on a new Demon 625 a couple of months ago. Have driven around local probably 100 miles or so since. I've verified the obvious such as bad fuel. I did just fill the car up but it will not run any better out of a fresh can of gas.

Anybody run into this issue with their Demon? Getting ready to pull it off and put my old seepy thermoquad back on. Car ran great with that for years. Just couldn't stop the slight weeping from the upper gasket so I dropped some bucks for a new one. Any ideas would be greatly appreciated?

Thanks.
