I've tried several different fuel pumps, the one that was on it, a good high volume I had and then a new one just in case. I have run both E10 and non-ethanol fuel with no notable difference cause I wondered if the ethanol was different down here, they don't even have non-ethanol in PA. Not to mention none of my other cars do it except maybe my 69 RT a little, also castiron intake but with a T-quad.

I know Detriot can get hot like PA but not sure it's the same as Fl, never been so I guess I cant say. What I experienced in PA was a hard hot soak start like it was bleed over after shut off. Cold it is 1 pat to the floor and electric choke works perfectly, even after sitting weeks.
