184 Cub Loboy Won't Start
This past week I've been get running the Cub I bought in KY last fall. The carb was gunked up and the governor and distributor had been tampered with. I removed the governor and made sure the two gear teeth were aligned. With the distributor removed I adjusted the distributor rotor so that just before the points open for No. 1 cylinder, I adjusted the drive lug so that it would fit up to the governor lug. As soon as I turn the rotor clockwise the high voltage coil wire sparks. While I crank the engine the timing gun shows between the 2 pulley marks. It tries to start, but won't. When I change the timing it backfires. I have spark to the plugs. Starting fluid almost starts it. I've intentionally tried to flood it, but so far haven't noticed gas on the plugs. I have a vacuum but haven't measured it. Dry cylinder pressure test is >70 PSI. I could change all the plugs I guess. I want it out of my garage to make room for more "stuff". I'd like to drive it out, but I'm starting to wonder. Appreciate any ideas. When I line up the rotor to a cylinder does it have to be #1 cylinder as long as the wires are in order? That's what I get when I watch Cspan while working on the tractor. My mind's getting fuzzy(er) Larry

John is correct, your timing is off.
The rotor rotation is clockwise. Points fire when they open. I think you should have turned the distributor counterclockwise until the spark occurred.
For initial timing I usually set the pointer just after the second mark - this retards the timing - fires just after TDC - making initial startups easier.
