1999 300 king quad starting/running issue
Hi all, first post here.
I have a clean low mileage 1999 KQ I bought off an old guy who used it to plow his driveway. Stored inside otherwise. Love the machine so far but it’s got some sort of running issue.
It’s been a bit cranky since I got it.
Recently was out on a ride, hit a hard bump and it bogged out and died. Would start and idle but bog when revved. Changed the petcock from “on” to “reserve” and it ran ok for the rest of the day.
Went to ride it the other day and it had the same issue on “reserve” now. Once I could get the revs up I could ride it but it would bog and backfire. Only way it would start/run was with full choke.
I pulled the vacuum line on the petcock (no fuel in it that I could see), plugged it and set it to “prime” and it made no difference
It’s about -5*C now and now it won’t start, got it to run for a second or two a few times but nothing beyond that. Usually it would start at these temps with full choke no real issue.
I pulled the spark plug and it’s soaked with fuel. It seems to be sparking ok.
Does this sound like a fuel or spark problem? Any ideas guys? Got me scratching my head.
