All.
I spent the season chasing what was thought of as a fuel issue. Everyone that I bumped into mentioned fuel fuel fuel but at this point I have something odd and I think its leading towards ignition unless I can get recommendations of new places to look.
The motor is a 1989 v6 150ETXF and it started as an issue where the motor didnt go over 3k. It ran as if it was hitting a governor. At the same time I needed to replace my fuel tank so I started following the lines towards the motor. New tank, new lines, 2 new pumps, broke down carbs and rebuilt them. Reran motor on pony tank and all issues still the same after motor work. I can dump the carbs and see that all bowls are full of fuel. Did pressure check and have 120lbs on each cylinder. When I pull the plug boots off the top 2 cylinders give an expected lob to the motor. When I pull any of the bottom 4 cylinders the motor doesnt flinch but I hear spark happening. I sprayed cleaner into the bottom 4 throats and nothing happened. The motor didnt jump or change at all. Every few rotations the motor has a miss and a burp, but nothing steady.
note..I also changed coils around and nothing changed. I'm at a loss.
At this point I am lost on where to look. Any ideas are appreciated. I would like to salvage some of my season in CT and God knows my wife would love her parking space back.
Thanks.
