I have a 1996 ZRT 600, that ran well for a small amout of time after i bought it then i died in the back of a field. Now it starts but won't move. I've figured out that the cylinder closest to the flywheel is not firing. It has good spark outside the cylinder but seems 2 be dead inside. I have tried different plugs, didn't work. Timing possibly? Carb looks 2 be working fine, plenty of fuel in it. Any suggestions?
