Hello JayO...
You are either not getting spark...
or
not getting fuel...
Start with the easiest ...
spray something flammable into the carb (aether, carb cleaner, WD40) and give it a spin. If it tries to start, it's fuel related... if not:
Check for spark ... Remove the spark plug... then with the plug wire attached and the plug laying on the engine give it a spin... if there is no spark ... you have an ignition problem...
Post back with what you find... and the next step will find the problem... :smile:KennyV
