First check the throttle cable free operation. Check rubber manifold couplings for air leak. If programmable firing control is used check the switch. Refer user guide.
Check program switch operation. This is coupled to the throttle cable. This switch sets the ignition timing advance or ******. This is called power mode operation switch.
Clean the carburetor with diesel or kerosene. Do the cleaning out-doors. Clean all the jet orifices with air. Use correct tools. Especially the flat blade screw driver tip.(end should not be sharp )
Note down pilot jet air screw position. Note the number of turns you screw out. This is needed for resettling the air screw. If it is a CV carburetor check the rubber diaphragm for stiffness or damage.
Needle jet is coupled to this diaphragm. Throttle cable opens the circular gate only. Due to velocity of the air the diaphragm positions the needle. Try the easy checks first. Finally main chain tension. Follow the solution given by Fixya GURU also

Be sure to put a new spark plug cap on your coil, it may have been the cause of the problem to begin with. It is possible to wet foul a new spark plug, therefore if the new plug got wet it could also be causing the problem. Do not be afraid to try third spark plug just in case the new one went bad. Also check the intake manifold for cracks or separation. The manifold could also have a cracked o-ring or a leaking gasket. An air leak on the intake side could be causing the misfire.
