Use Clean, high quality 2 CYCLE OIL. I spent ages trying to get it started, I already took the spark plug out and cleaned it. Read on for the full scoop. If you had said the engine backfired and was hard to start, but no flooding, I would also look at low fuel pressure. A pull start is not required nor is it included in the kit. If no compression is present in any one cylinder it means a mechanical malfunction has occurred while low compression could just be the sign of worn internal engine parts. I pulled the plug and cranked. If its a lower octane, it will puddle and flood the system. An example of this would be for the first engine oil change. You replaced the carburetor, likley you have debris in the needle valve port from old fuel line, or rubber from fuel line. A two stoke engine fires at every revolution.

Since a 2 stroke has combustion once every crank cycle (whereas the 4 stroke combusts once every 2 cycles) then the pistons top temperature can get high enough to melt it at high engine revolutions with the timing advance equal to that of a 4 stroke engine. After this 4 hours has past the meter will reset itself until 2 hours before the next scheduled service.
