Thread: 670 Holley fuel question

Tweet

I have a 670 holley cranks good runs good but in a sharp turn or quick stopping its chokes down like no fuel there. I've checked the site plug and the gas will come out if you just shake it just a little. Looking for some advise.

Ideally, gas should come out of the side plugs without shaking it. Not spilling out or pouring out, but the level should be as high as the side plug. Also check and double check for vacuum leaks. Have you verified how much vacuum the motor makes? With a long piece of hose you can set a gauge up in the car and cruise around and get some readings this can be helpful in a diagnoses.

Ok, thanks

Another thought, as your car sits normally is the carb sitting level? I ended up using an aluminum 5 degree spacer, thick side to the rear, to get mine level. Hard to get the float level right if the carbs sitting at a steep angle.

That never crossed my mind. I will check that also
