I’ll try to post an update weekly for a while, see if I can commit to that much communication.
Installation of the new carb hasn’t helped much. I’ve certainly not tuned it properly just yet, and I’m pretty sure my timing is pretty close to advanced 30 degrees, the suggested timing for this motor. There’s a pretty solid miss that I’m still tracking down, not happy if I have to get some better plug wires, again. The plugs also may get replaced, and I installed an electronic ignition module to replace the points which may or may not be an issue. All in all, it wasn’t the most rewarding tuning session.
Good news is that a compression test on all 4 cylinders came out over 150 psi EACH! It was within 2-3 lbs on each cylinder, and the fittings are pretty solid on the tester now so I have confidence in the reading. What problems I have now are very likely intake and or timing. I also need to lash the valves now that there has been some break-in time, that will be for the next tune up.
Electrical install is about 80% done, but the rear brake pressure sensors are not helping out on battery life. Seems the brake lights stayed on a good while, and semi-melted the entire assembly! I’ll need new lights, fortunately these were cheap ones I doubted already. The rest of the electrical system worked out perfectly, and I plan on putting a whole-system cut-off for the battery in the near future.
