try easy steps 1st check for spark by taking plug out of head and holding it on metal engine part and turning over the engine to see if spark ok could be knackered spark plug holder /lead
check fuel is getting to carb/ barral by seeing if plug is wet after a few trys
if both ok next step could be finding out if you have sezied top end (barrel/piston)or imomblesr/cdi problems
