How's it goin'? I'm new to this forum and also a first time owner of my first ATV. I've ridden several in the past,
but; this is the first one that I've owned. It's a 2005 Grizzly 660. The only problems with it are it has a rough idle
and will eventually stall. Is there a carb adjustment (air/fuel mixture) that can cure this problem? When riding the
problem doesn't exist. The only other problem is that I can't get the ATV to shift into park. Is there a linkage adjustment that can be made to cure this problem? Other than those two issues, the bike is in real good shape.
Are there any known problems that the Grizzly is know for that I should be aware of? Thanks in advance for your
help. I look forward to chatting with you all.

 

My best guess is your choke is probably sticking. Sometimes your plunger gets gummed up and sticks open a bit. Try unscrewing it from the carb and clean and lube it with lite oil.
