I am still learning about the 2-stroke engine.
At the end of last Summer, I rejetted my HT to a #65, and I have had nothing but awesomeness at full throttle. But starting was always an issue. I figured the learner configuration messed everything up. As the weather got colder, I'd have to pedal more an more to get things up to speed.
I use the delortto clone carb (RT) that has the semi-automatic choke option. That thing has never worked for me because as soon as the engine popped, it released. So I just ignored it. My most recent starting technique was to pedal and pop the clutch with no throttle, keep pedalling until some engine heat would build, then I could gradually work in the throttle until I got continuation.
Full throttle application made starting worse, so I figured the mixture was too lean and more air made it worse.
Also, I noticed an occasional problem when motorbraking after a fast, high RPM run. When starting from zero after, the engine would act (to me, at least( as though the fuel wasn't feeding through. Not always, but often enough to be a pattern. It was very similar to my slow startups.
For whatever reason, I simply covered the intake to impede airflow with my left hand as the engine chugged at low RPM and - ZIPP! - the thing took off. All I ever needed was a touch of choke! I get a bit of fuel spitback on my fingers but that's nothing.
I am slow to learn sometimes, but I can learn.
