Kitten is back running. What a long strange trip of events this problem was. Taking full ownership of stupidity or bad timing, thanks in advance for all the input that got resolution.
Around December 4th I jacked up the kitten to take a look underneath. I left it like that for awhile. Next time I tried to start it it was flooding out. Here I cranked it so much the battery died so I used my jump pack. The battery starter and ground cables were junk so I swapped in some temp ones I had sitting around for and continued the troubleshooting. Here I think I cooked the electronic ignition compounding the flooding issue.(This info would have been nice to have at the time.)
Convinced my fuel pump rebuild was bad I sourced a new pump and created the same condition of flooding. Next I started troubleshooting the ignition. New coil, wires, and found no spark. Turned out the ignition module was bad possibly from the jump starting maybe leaving the ignition on. New module arrived with new matching coil and wires. Here I get it back running but off the pump on iv gravity feed. Didn't run right though missing and excessive fuel.
Back into the carb, new float and NOS inlet needle with extra washer. This is believe was the actual issue but hadn't figured it out yet. Then into the choke which has been messed with by the different screws, broken air vent, and orientation was wrong in hindsight. Cleaned took it off back on. GMoose and the internet were helpful.
Now I am defeated again. Still thinking fuel pressure of pump. Machine down the spacer which was 2mm larger after some feed back from RedSquirrel and go back to original pump. 6mm is the correct on for this year. Same issues. Flooding. It always fires and dies. I check compression and tear into the ignition again checking firing order and plugs. Here #2 plug has no spark. Replaced all four plugs. Now as I crank it it runs on the starter and dies but runs fast.
Installed fuel pressure regulator after feedback from the Princess and internet same issue. Runs on the starter. Took the bowl and choke off dozen items swapped everything same issue. Runs fast on the starter. Soon as I let go of the starter died. WTF!
Spoke to Obsolete Anglia for awhile the other night he was stumped. His specialty is the pre 100E if that helps anybody.
Light bulb today thanks to the fresh SNO arriving! Why does it run so fast with throttle on the starter? While waiting for parts I replaced the batter cables placing the battery on the left and the starter on the right. Well turns out the were opposite originally so the ignition now was only getting power when depressing the starter.
So good news is I now have it figured out and all the parts I bought went over better with the wife because of how frustrated I appeared.
First tracks after 30 years tomorrow to celebrate!
