I have replaced the ignition in my 89 OMC 2.3L. New plugs, wires, new Mallory Dist. with electronic ignition, new mallory coil (not a resistor coil). Timed to specs. And reman carb also.
Only fault I could find before going to lake today was coil run voltage was 7.5 volts instead of the 9 volts I have read it should be on this site.
Ran fantastic for about an hour. Climb out, top end, idle, stopped and started a few times- all real smooth. I was running about 4 T RPM when I felt the motor drop rpm a few times and I throttled back and it died. Would not restart at all in neutral. If I advanced the throttle out of gear sometimes the engine would start and run above 3 T RPM but if I reduced throttle below 3,000 it would always die and I could not keep it running to get it into gear.
I have not tested my fuel pressure.
When I got home I put a spark check device on the number one plug wire and it looked like I had blue spark across a gap of 20 on the device.
Any ideas?? weak fuel pressure? weak coil voltage? I am lost. Thanks, Ed
