So I cleaned out the air cleaner system, and rebuilt the carb. It's going into a lower idle without stalling than before, which is good, but it still stalls out if you try to 3rd gear. It is running an inline fuel filter (which I'm not a fan of) for now, but I do have the sediment bowl assembly, and have a new fuel line on the way to convert it back.
Any other ideas that I'm missing?

Compression tests, dry then wet. Post results.
If compression is satisfactory, a complete engine tune up.

Re: Stalling in 3rd Gear
Hello,
I'd check timing first.

what makes my cub very rare is that it's the only one I've ever owned.

Re: Stalling in 3rd Gear
Mine would sputter and die when under heavy load or taking off in 3rd gear right after I bought it. A quick timing adjustment was all it needed to work great again.

Re: Stalling in 3rd Gear
Thanks for the ideas guys. I'm leaning towards the compression issues, nothing sounds "off," but I am getting some blow-by smoke out of the oil fill at low rpms. I'll have to track down a compression tester and see what it says.

Re: Stalling in 3rd Gear
Low power and blow-by from the oil filler = worn rings allowing compression to escape into the oil pan. You're on the right track to check compression. Poorly seating valves = hard starting but no blow-by from the oil filler. Good luck. Stan
