Not sure what year this Yamaha Wolverine 450 is but she was running perfectly fine yesterday and then sputtered out. Never liked to idle and was a pain in the ass to start. Now it just turns over and pours white smoke from carburetor intake, smells like burnt carbon... Almost like the i soaked the cylinder in sea foam. Any ideas? It's got 1600 miles on it. Thanks

Sounds like it's running a little bit too lean. Try adjusting your mixture screw and richen it up a little bit.

Good idea.. I pulled the plug out and sprayed starter fluid in the cylinder with no avail. Not even a slight pop. Thinking timeing chain slipped and I bent a valve or a seal went bad. Going to rent a compression tester now.

Try turning the motor by hand. If the cylinder went up and hit the valve you would feel it stop turning.
