383 Cruising Issue

I'm not trying to make an argument. But I'm going to say that I'm not following your logic. The O.P. said he's turning 4,000 rpm. But even if that's not accurate, it seems that the O.P. is running high rpm. And high rpm would use a lot of fuel and make a lot of heat. Which seems entirely relevant to what the O.P. considers is happening (he said it acts like it's not getting fuel). And then states … any thoughts? And that's what we've done … added our thoughts.

So I'm not following what you're finding wrong with anything AJ or I have posted.
