Not To bash on you or anything. But 2 stroke carbs can be very tricky if you dont know what you are doing. Id say you are barking up the right tree starting with that carb good luck!!

Blaster Problem 01

If you haven't fixed it yet you might check the throttle. If it has a stock throttle and carb, this model has a feature called TORS, that means throttle override system, it shuts off spark in case of a stuck throttle, if the throttle is not adjusted properly, meaning not enough freeplay. Now thats freeplay not foreplay! Or if the tiny switch in the throttle assy is damaged it can and will have a missfire. Check the freeplay, about 5mm on the lever is close and check for damage to that switch, just follow the wires into the throttle housing.
