Rode some creeks today, but, had to stop a little sooner than I had liked. Upon climbing steep inclines the grizz starts cutting out and will die if the incline is steep enough. It reaks of raw fuel. Once level, everything is fine until hard acceleration, or, another hill. I have just turned 50 miles and it sucks 'cause I'm right at 20 hours and was prepared to change the oil and let her rip. Now I have this issue to deal with. My buddy has an '02 kodiak and said yami's are a little rich and he changed his plug real soon too. I pulled the plug and it is not wet... it looks fine it's black around the seat and the electrode is light tan. If the plug is the problem why is it only acting up on hills? It started this early, but it was very mild. It steadily worsened until I was unable to traverse some hills. Anyone heard of this? Thanx for any advice!
