Fighting a crazy miss!

Got a 71 250 6, bone stock.

It has got a crazy miss.

It will run perfect until you rev the engine. Number one goes away. Then it runs awhile and comes back!

All new ignition. Valves set twice. Carb rebuilt.

Help.

Woah...at first I thought you had a crazy lady on your hands.



Have you checked the fuel filter... how about checked for water in the fuel?

Re: Fighting a crazy miss!

Also check for vacumm leaks at the intake manifold to head area. Another thought, check for eccess wear at the distributor shaft/bushings (Dwell inconsistent).

May those who love us, love us, any of those who do not love us, may God turn their hearts.
And if God is unable to turn their hearts, may he turn their ankles so we may know them by their limping.

A man who works with his hands is a laborer; a man who works with his hands and his brain is a craftsman; but a man who works with his hands and his brain and his heart is an artist.
