The first thing i check is electrics before the carb. No spark or intermittent spark could be your problem. You work by ilimination electrics first. Squirt some 2 sroke starter fluid into the plug hole also onto the plug. 2 sroke starter fluid is mostly ether. If it does not go when using a starter you have no spark it should fire and burn the starter fluid then go from there. Naturraly you have a good battery, Blocked filter in the carb or fuel line. Work by ilimination. 2 stroke gas engines are very simple engineering. Let us know if you find the problem.
