Yeah, I’m thinking it’s something other than a choke problem because it should still start pretty easily without it. It’s not that cold this time of year either.
I’m thinking fuel is not getting from the tank to the engine properly after it has been sitting for a while, or 2 stroke oil build up inside.
Do a test. Next time you get it started, let the engine sit for 2 days. It will be stone cold my then.
Try starting it and if it starts easy then you know it’s not the choke.
