'86 Yamaha Enticer Fires then stalls...

My son has an '86 Yamaha Enticer that has just bit the dust (now that we have snow).

Has been a fabulous sled for two seasons and literally just died the other day and will no longer stay running. It will fire for a second or two, then cough, and die. Sometimes it lets out a little muffled backfire when it dies.

New plugs have been installed, gas is getting to the carb (plugs wet), have spark, compression is 120 mag and 100 PTO. I know that is bad because they're not balanced, but is it possible we've been just running this way for a few years now?

I have my doubts it's the carb because it's always run absolutely perfectly and the engine will still fire, but just not as consistently as it used to.

Your thoughts/help would be appreciated before I start digging in deeper.

I would pressure test the motor. That 100 lbs sounds like a problem too. Plug the inlet ( carb boot) exhaust port and pump about 8 pounds of air into the pulse line. If the pressure doesnt hold spray soapy water on the crank seals, head spark plug hole and where the crank case goes together.
If your not familiar with this test I can explain it better if you want. You can make the tester with a bicycle pump, small valve and a cheap pressure gauge.
