It could be a number of issues, rings, small air leak or timing or electrical (startor or cdi)  |

I wid try Norrys advice first,
Turn the petrol off before switching the engine off then try and start it wi the petrol still turned off.

It wilnae make a blind bit o difference if you turn the petrol off before you switch the engine off, or efter, as long as you turn it off but try starting it wi the petrol turned off tae see if that helps

Hot starting problems can be a sign of the stator on its way out...

Okay update....noticed carb top was not sitting on carb properly, when I took it off it appears that the previous owner has threaded the carb and put a peice of plastic raw plug in it and then put bolts back in to try and give it something to grip oan. Anywaygot carb retapped and new bolts oan. Also added a 12v coil and new stator. Appears to have done the trick.
