1641 with 1 cyl no spark
 

I started my 1641 today to put on the snowblower and it was shaking and smoking a little. I felt the heads and one was cold. the rt side has no spark, the plug is wet. Is this a coil/plug wire or can something else cause one side to die. I don't know much about Briggs vanguard twins. Thanks Rick

I fixed it. It was the coil. A dried up dead mouse and a bunch of hair was around it and it must have overheated it. I blew out the hair and it runs great again.
