Hi LTRM;
The Cobra vaporizer - regulator that was OEM original, was it built for N. Am. use or was it built for EC use? Then the next question is, your "primary" fuel pressure is good, but the "secondary" fuel pressure spring that is in use with the replacement vaporizer - regulator, is it the right one? The outlet fuel pressure from the vaporizer - regulator is susposed to be 6 inches negative W.C. at idle and 13-8 inches negative W.C. at full speed. N. Am. built Cobra aren't interchangeable with the EC's.
