Ok guys, I know ive posted about 1000000 topics on my MXZ. But, I just attempted to start it up a few mins ago in the garage, and this is what happened. Started w/ full choke on 2 pulls, shut choke off, had trouble idling for a minute then got out of it and idled fine. Pressed the throttle real quick so the clutch engaged, then let the throttle go, and then engine died, and it WONT start back up. I pulled about 25 times, WILL NOT start. So I decided to look at the plugs again..... This is what I found. Clutch side cylinder was a vanilla looking color and was wet, chain case side was black and wet. So the clutch side was fine, but the chain case side was way too rich. A few of you guys said it may have been an air leak a while back, but I checked the airbox and carbs and everything, everything seems to be right. Im pretty much out of ideas now about what to do. ??? ??? Do any of you guys have any ideas?? Me and this sled havent gotten along since day one. :angry: Also, the exhaust still leaks from where the pipe fits into the silencer, I tried that gasket maker/sealer stuff and it didnt work. Cant figure that one out either. Anyone have any ideas?? getting kind of frustrated now :angry: :angry: :angry: :cussing: :hallo1: !!!
