Here is the story, Grandpa has a first gen I think its 10 years old polaris ranger 400cc. Problem showed up this year serviced it this past summer, about two weeks later said it wouldn't run right/start. Check it out the two week old plug is all fouled, clean it off with a torch and starts up, So I replaced the plug. Fine for about a month than the same thing. Alright decide to take carb off as all adjustment are sealed. open it up and the thing is spotless. clean it anyway, put back together and open the adjustments. Get carb back on everything seems ok.
well long story short through the last summer/fall he went through four more plugs. Nothing changed about his use, still uses the same fuel(we have a station that has one pump with pure gas yet, he always gets that) I called two differant dealers, one said they replace these carbs all the time, the other said they have only replaced two on the rangers(should of expected that
Carb Is $500 any ideas on something I might of missed, may just have to do a carb. As a side note this thing from new never seemed to want to idle nice. Never needed the choke to start it but always had to step on gas to start it.
