First, it's a friends tractor, not mine. But I'm more mechanically inclined than he is, so he asked me to look at it.
Couldn't get it to start, not even a chuff using starting fluid. Found the carb had gas flowing out of the throat. Took it off and got the basic rebuild kit. Replaced the needle valve, seat and gasket. Yep, tightened that sucker down good, a small machinist square fit across the slots just fine. Adjust the floats to spec using a 1/4" drill bit between floats and gasket. When I put it together, I can hear the floats move up and down when I flip the carb over. Put it on the bench, rigged up a little fuel tank using fuel line and a funnel. Sat there for 2 days, never leaked a drop.
Installed it on the tractor this AM. Checked and cleaned Dist. cap and coil contacts. Checked ohm readings on coil. Checked firing order of wires to cap and plugs. All correct. Took out plugs, cleaned, gap, reinstalled. Turned on the fuel, hit the key and it fired right up. Did the happy dance. Let it run for about 10 minutes to charge the battery up. Shut it off. Went to restart, and wouldn't fire up. Pulled off the hose connection to the carb input, and sure enough, fuel sitting there. Grrr... Carb doesn't seem that old, is aluminium. Don't know what else to do with it at this point. Also, the distributor shaft has a lot (IMHO) play rotationally. Like there is excessive wear between the distributor gear and whatever drives it.
Background note - Sometime in the past, it was converted to a 12V Neg system with electronic points. And it has been running fairly well up to this point. Suggestions?
