Hmm, I'd be starting to look into the bogging. 2 Strokes often need carb clean's after sitting for a while, that'd be my first go-to. And throw in a new plug and check the air filter condition.
Get it ticking over, and once it's warm jam the throttle back to full throttle as fast as possible, if it bogs your carb settings are out. I wouldn't mess with it until you get a manual though and I'd do a plug chop.
