I believe I'm getting good spark, but that's just while cranking it over with a plug out. I'm not sure how good or stable the spark is while running. I don't really think the coil is the culprit though, but I figured it was an easy $18 process of elimination, since it obviously wasn't wired in right anyway.
The engine does warm up very quickly by the way, much quicker than I would think it should. And no, no choke ever. It won't start I use the choke, even when cold.
My two best guesses at this point are exactly as you said Steve, I'm wondering if someone screwed with the carb and drilled something out on it. My other guess was the distributor having an issue somehow. I didn't think about the bushings on it.
Royse, I've cleaned all the filters and screens. The sediment bowl and screen look brand new. I believe they were replaced when the carb was rebuilt.
I have very good flow. Someone put an inline fuel filter in front of the sediment bowl. So I pulled each part of in turn, and checked flow. I checked the fuel filter, blew through it, no restriction at all. I checked flow with the bowl off and it's flowing at about the same rate as directly from the fuel line, and the drain on the carb is the same. I haven't measured it, but it puts out about a steady 1/4" stream. I'll try draining it in a pint jar and checking it. The inside of the gas tank looks new.
The history of the tractor is that it was in a barn in a farm somewhere, a guy bought it just because he liked it about 5 years ago, paid to have a bunch of work done to it, including wiring etc. Then it sat, no one used it, he died, and his sons sold it. I believe before they sold it the sons paid to have it gotten running again, probably why the carb rebuild looks so fresh. The wiring conversion on it appears quite a bit older, the carb looks fresh, in the past few months or less. Everything is bright and shiny on the carb.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
