Hello Joey my son drives his bike on the fuel blending of 2% oil maximum or else it eats plug. Here is a email adress to a place who sales parts in Sweden nilssonsmotor@telia.com Do you know that Huskvarna is a swedish bike. About the carburator a tip is to put a liitle bit grease at the top where the gaswire enters the cab to avoid sand in carb. about the airfilter clean it in gasoline and after it dries rub in ordinary motoroil just so its litle oily. Hope you enjoy my tips . Johny
