Timing question 318 with LD4B

I saw 1.5 psi fuel pressure at 3K RPM. If you think that's enough, well.....I don't know what to say. What do you think will happen to that 1.5 psi under a LOAD going uphill, or trying to pass a car? Or get on an interstate ramp. The carburetor certainly DOES care about fuel pressure. If it sucks the float bowl dry before it can refill, then there's a problem. A lot of times though when one shuts off like that when you let off the gas suddenly, it's because the idle air screws are out of adjustment. You might put a vacuum gauge on it and adjust those. But that's going to do nothing for that fuel pressure. IMO you need to track that down.
