The Coleman PM 1850 manual calls for a spark plug gap of 0.028" (0.6-0.7 mm). Mike

Process of elimination is needed, check/replace spark plug->check ignition coil>check pulse generator>check stator/AC generator>check kill switch. if all is well then check key switch for functionality if applicable to rule out CDI Alot of bikes use a 2piece ignition coil, try pushing the plug cap onto the lead by screwing it on like you do a bolt to a nut. Also try disconnecting the kill switch. for pulse generator, stator and ign coil you need to know the resistance values specific to the model to know weather they are past servicable limits. only other things are to make sure these wires are properly connected: -stator to ign coil -cdi to ign coil -pulse generator to cdi
the plug gap for generator is 0.70 mm
well if there is no spark, the distributor is bad.
NGK CR8E is the best spark plug to replace the original
faulty crank angle sensor in most cases

The correct gap is .035.
Remove all cables from the generator. Connect battery's + (plus) to the generator's A and then connect battery's - (minus) to the generator's F (field) for a second. Might give a small spark, but that doesn't hurt anybody.
The 1984 Honda VF1100-C is not adjustable, You first check the Ohms on the coils and then check the ohms on the Pulse generator 480 ohms, between white/yellow and yellow wires that is 1 and 3 cylinders then between white /blue and blue wires 2 & 4 cylinders There is a adjustment on the pulse generator Its under the right side cover and uses a feeler gauge to set and they set from 0.006 and 0.024 So you test the pulse generator by unplugging it from the plug under the seat and check it by doing the above with a Multi-meter if you have 480 ohms there good then adjust them and set to above with a feeler gauge. Then if the timming is still not right you then change the spark boxes.
