Hi i have just got my puch powdercoated from a shop in the UK and looks really nice. i put it back together slowly with a mate not making no mistakes then i put some fuel in that my mates mum had in a fuel can (mixed but didnt no what mix) anyway i kicked it first time and it started had nice smoke out of the exhaust to. This was great then it stopped we still have a little bit of fuel in the tank (not much but enought to get it started i think). I took the sparkplug out after a few trys of kicking it over and the tip of it was black. So is it just i need to put some good mix in there or have i done a silly mistake and broke it.
