I have a 2005 grizzly 660. Was riding it last month and it became really boggy so one I got it home I noticed the carb boot that goes from engine to carb had a large tear in it. So I ordered a new one and put it on and now it won’t start. Just put a new plug in it as well and it still won’t start. It has spark, gas, and all the air filter and hoses are hooked up. Once in awhile it’ll backfire when I try to start but that’s it. Any ideas? Would really like to get her going! Been sitting too long for my liking
