Yea, What he said , bad - very bad. Mix up some 2 stroke mix ( gas and oil ) and use that for your firing test. You can put that directly into the spark plug hole. I also use a spray bottle and you can continue to fog into the carbs to keep a unit running. If it keeps running this proves the electrical portion and you can concentrate on why you have no fuel up to or through the carbs.sesnopro said:do not use starter fluid it start up your sled it is really bad for the engine. put in new plugs. how old is the gas?
