[QUOTE="ben2go, post: 55768, member: 751"] Don't run a 2 stroke motor out of fuel.It requires the oil gas mix to lubricate the internal parts.Gas is a shady subject.I don't use gas over 2 or 3 months old.Some people have kept gas a lot longer with no problems.Your motor is water cooled.If you have water muffs or a garden hose adapter to connect a water source,it's ok to run the motor when it's not in a body of water.Only run the engine for short periods,10 to 15 minutes.I'm no specialist but this has worked for me.Obtaining an owners manual may help.Since you have kept your motor stored inside,it shouldn't need much work.The things I would do,would be replace the spark plugs,make sure the gap is correct.This is very important on 2 strokes.Drain and refuel with fresh fuel and new oil.Try to avoid ethanol blends if possible.Ethanol is hard for a 2 stroke to burn,it eats up rubber parts and gaskets,it also has a tendency to absorb water.Hope this helps.
