Trying to start an engine sbf 289 with a double pumper Holley. I rebuilt the carb with a 6.5 power valve. I crank engine and it seems to ingnite fuel a tad bit, but cannot sustain any revs. Seems like its flooding out.
I have checked, fuel to carb, spark, and dont see any vacuum leaks, valve movement seems ok..
Electric fuel pump pressure is just under 5 lbs, but fluctuates from under 5 to 0 back and forth while cranking. Holley carb float level is correct.
- will engine with a high performance cam not start if power valve too high a rating, do I need a 2.5 or 3.5 power valve?
- would car not start if electric fuel pump not quite maintaining 5-7 pressure?
I would think car would start and then either run rough or die quickly, but engine wont fire up and rev.
