1998 C40LTRW will not idle with lever closed. Performed the "sync and link" as the service manual said. (20mm gap at retarding stopper, adjust rod to align pointer with marks on CDI. 25 atdc when retarded and 7 atcd advanced. Also adjusted carburetor linkage as the manual said. All adjustments were minute, as the motor was close to factory settings.) After adjustments the motor improved. runs smoother. The motor dies when the throttle lever is about 1/4 open. Cannot get the motor to idle with the lever closed. The spark looks weak on all three cylinders. and i cant get a timing light to flash on any of the plug wires. but the plugs are getting fire. the motor runs! just very weak. Do i need to use a timing light to adjust the screws on the magneto lever (moving the pointer on the CDI)? Could a bad CDI or coil cause a weak spark? would it even run? Is it likely that all three ignition coils are bad? All help is very appreciated. New to the forum.
Thanks
