Well, I think I fixed the carb and lean sneeze problem, but now another promblem arose. Put it on the water and now it idled a little better, but ran rough at high speed. I ran it in the test tank. Ran rough like one cyl. was intermitantly cutting out. Sure enough,when I pulled the top plug wire,nothing happened except it ran a little smoother. Stil some cutout but not as bad. Pulled the bottom and it shut off. Back to the shop. Put the spark tester on it and initially got good spark on the bottom wire. Reset the timing by very carefully setting the gap. Lightly filed the points (before I set them) and cleaned with a little lacquer thinner and blew dry with compresser. Put the spark tester and now get unreliable spark flom both plugs, intermittently. Sometimes they fire; sometimes not. No mag plate wobble. Mag plate grounded to block OK.
You will remember: I have switched coils. New condensers. New plug wires. Disconnected the kill switch at the points. New points. Used different spark testers to be sure my homemade one wasn’t the culprit . Tried setting the timing with a multimeter. It seems like, whenever I fix something, something else goes wrong. Must be something loose. Something I am over looking. It was running like a champ WOT, but coughed at idle. Recleaned the cab for about the sixth time and now this. I refuse to give up. Too much emotionally invested.
