Smile Re: Sudden idle problem

You should make sure the power connection for your HEI is rock solid.
Then, you should get an electrical tester and make sure you have 12 volts to the distributor....not 8, not 9......12 volts.
If you don't, the distributor may not fire correctly and it will give the impression of a bad tuning or carb problem....and this degradation can happen within the wiring. (ask me how I know)

....for some men, there is experience, skill and effort....for the others...there is visa and UPS LOL
