Long story summed up, low rpm miss. Since we've owned it. Way back when, I found bad points, swapped carb racks and recently no valve lash on the #2 intake. I adjusted it and ran it a few miles. I cleaned the carb passages on the bike.
I ran a leak down test all cylinders were 3 to 4 %, I gapped the points, checked timing, checked the advancer, checked the dwell. Did clear tube test and cleaned jets 1&2.
Next day, Re-adjusted all of the valves, dwell, timing, I figured out how to get the compression tester on it, 165, 155,155,170. #3 exhaust was hotter than the other 3 when spraying water on it.
Today, I did the clear tube test on 3 and 4 and re-cleaned the jets. The #3 pilot jet seemed larger and after checking realized it had been drilled. I replaced them both. Now It seems to have a little more vacuum and I was able to finally synch the carbs with the Carbtune. This turd might actually idle good now. I think the timing advance is still too loose. Idle rpm's wander a little.
My brother wants to ride, he's 84 now. I hope it goes well, if not it's what he wants to do.
