Re: Polarity tester
Am I confused? If you change the polarity of the battery ground as in 12 volt negative ground, you have to reverse the ammeter leads or the gauge will read incorrectly, as in backwards. Why would we...

Re: I give up
Where does the term 1-1/4" come from? I've never seen that before, anywhere. All I've ever seen is 1" or 15/16". Verify that the fuel level (not the float height) in the float bowl is correct....

Re: Idle Mixture Screw
Shew01:
With the vacuum gauge hooked up, you turned the idle air adjustment screw full in and the car dies (as it should). Correct?

Re: Idle Mixture Screw
Shew01, remember, that a professionally refurbished carb can be immediately contaminated by dirty fuel. Is your sediment bowl clean?

Shew01, suggest you use a torque wrench to tighten those pretty plugs with new gaskets to 25 foot pounds or 300 inch pounds.

Re: help! clutch won‘t disengage…
As I recall, if you remove the floorboards and the clutch inspection window cover, you can see the springs as they come past. Use the hand crank to turn the engine over???

Re: Idle Mixture Screw
Am I confused? 3.5 turns out on the idle air mixture screw would be allowing additional air into the idle circuit. Wouldn't this compensate for a rich mixture, rather than a lean one????
