my friend has a 04 brand new rancher. he ran out of gas out on these horse trails and we pushed it a ways to some persons house. we ask if we could have a little gas if they had it. the guy came back with a tank, and we poured in just enough to get home, and after he put in a quart he lifted the can out and put the cap on, and the guy said that is chain saw gas. we said o no, because its a 4stroke, and the chain saw gas is mix. we said thanks and rode home anyway, it rode like normal, but does this hurt it, or would it hurt it just that little ways?

 

it wont hurt it.. just make it smoke a little from burning the oil thats in the gas.

 

it wont hurt at all if anything it will clean it out a little my dad used to take my and run it in the push mower it smoked a little but never hurt it

 

You shouldnt have a problem. I would drain out whatever is left in the tank, throw a new plug in and let er rip.
