Set your engine on the correct stroke & position for installation, as follows:
a) Remove your rear spark plug only.
b) Kick until you feel front cylinder compression; rear piston will be on the way up.
c) Continue turning the motor until the rear piston gets to the top. At this point, the correct
front cylinder advanced timing mark will be just appearing in back of the inspection hole. Continue until it is centered. Remove stock
circuit breaker and mount clamps. Install the drive shaft onto the drive slot in your engine. Cut small spring in half, and install 6-32
screws in the drive housing (with the spring pieces under the heads). Screw in half-way. Now place the drive housing over the sleeve on
your engine.
Before you can tighten the two set-screws, you will need to set the proper height; temporarily place the supplied shim/gasket over drive hex, to provide for proper end-play of drive. Remove magneto cap. Set magneto rotor so narrow cam lobe is located counter-clockwise from cam follower as in the picture 2, and breaker points are just opening. This is your correct advanced timing position. Maintaining this position, place the magneto on top of the drive housing while fully engaging hex. Lightly snug the magneto studs to the drive housing (use spare nuts supplied). Twist the drive housing (not the magneto) clockwise until it stops (tail of 6-32 screw hits stud). Now tighten the two set-screws, using loctite.
Disassemble magneto from drive, remove shim/gasket. Apply grease to hex drive and magneto base plate. With engine and magneto in advanced timing positions as outlined above, install magneto with washers, lockwashers, and stopnuts. Tighten nuts until lockwashers begin to compress. Attach the large spring between front (retarded) adjusting screw and rear magneto mount stud. Set advanced timing (rear adjusting screw) visually as outlined and shown above. Static timing is all that is required. Timing can be dialed in exactly by using Morris Magneto p/n KATT, timing and testing tool. We do not recommend the 'cellophane' method. Re-install cap (make sure coil springs line up), and tighten so gasket does not compress more than 25%. Retard timing adjusting screw should be set so that end of magneto moves approximately 3/4" from advanced timing position. Retard timing is used for starting and can also be used for idling. When riding, magneto must be advanced, or you could overheat engine.
With the proper mounting nuts tension, magneto will stay retarded for starting and idling. As the
throttle is opened, vibration from the engine permits the spring to pull the magneto advanced
automatically. For racing applications, we recomend a stronger advanced spring and/or greater
hold-down nuts tension. Stud on side of magneto is used to "kill" magneto with a grounding toggle
switch or lever (p/n KSL). Do not connect to your 6 or 12-volt system!
Stuff to know: The long-lasting OEM-type points in your magneto have been set at .015,
and will require no attention for years. When replacement is necessary, use Morris p/n P5 and
condensor p/n P6. Use only original type cap, gasket, points and condenser. Initial spark plug
gap, .020 -.025". Due to the hot spark, you can expect the gap to burn larger somewhat faster than with a
battery ignition. Use of a single-fire module, Morris p/n MSF, may help prolong plug life. Use non-resistor spark plugs.
Use copper or stainless steel solid core (non-suppression) spark plug wires (Morris p/n MWS).
