Stalling in 3rd Gear

Postby FredS » Mon Apr 25, 2016 3:22 pm

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.
I have an excuse. CRS.

Hello,
I'd check timing first.
what makes my cub very rare is that it's the only one I've ever owned.

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.

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.

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
