Hi, Im wanting to check the float levels on my holley (2) 750 carbs. both carbs are installed on the vehicle but Im concerned about doing this with the engine running. the motor has a mech fuel pump and reg just ahead of carbs. Is this normally done running or not? If not what is the procedure?
thanks jim

getting the float level correct is only part of the issue you'll face, youll need a steady 5-6 psi,
and enough volume of fuel even under higher g-loads youll see under hard acceleration.
