I will do that test

I tried it with a smaller 12V pump from a VW, that only put out around 4-5 PSI. But when it didn't work I went with the Stock CIS fuel pump and the PMO regulator as everyone here was doing on the CIS conversions.

The pump had the internal check valve in it for the supply line. Years ago I had a hard start issue and put in an in-line check valve. I looked at that and it seems to be working fine.

I just can't figure out what could be causing the poor start/ no running issue with both CIS AND carb now.

I can't even get it to run long enough to double check timing, but it starts right up if I prime the carb. then it runs like poop and dies
