  2. I have a 2002 grizzly 660. I just bought it last week. It had sat for about a year. I knew going in that I was going to have to spend some time in the carb. I took the carb apart and sprayed it with carb cleaner and blew it out with compressed air. I cleaned out the fuel tank, replaced the fuel line and new fuel filter. Filled with fresh fuel. Started it up and set the idle. I rode it for about 3 hours yesterday. Then it developed a miss. At idle it would go put put put miss put put put miss. If I didnt not add some choke then it would die. The miss wouldnt go away it would just idle it up fast enough for it not to die. It progressivly got worse. It also would have that same miss at slow speeds steady throttle. If you give it lots of throttle it runs great and the miss seems to go away. When it misses like that the exhaust makes a whistle sound also. Today I pulled the spark plug and replaced with a new one. It did not help. old plug looked good, but it was two heat ranges to hot from stock. Not for sure why that was in there. My first thoughts would be the pilot jet maybe. Pulled it out and its clean. Is it possible that some trash got in there with all new lines,filter,fuel and a clean tank. Thanks in advance guys, kinda stumped.
