I forgot that your light wires come out of the mag too and trace them to the headlight and tail light and then the other wire if there is one is the kill wire and trace it to where it goes - switch etc.

The toggle switch could be for lights only and the middle is off and  lights and high and low on the other two positions. I killed my old Servi with throttle back to idle and kill with the compression handle bar side.

Texas is good to live in because we have hotter than hell in July and August, nice fall days in Sept. Oct and 1/2 half of Nov. Then some cool days in 1/2 of Nov. Then hit and miss freeze and warm days in Dec., Jan. and Feb. Very nice days in parts of Feb March. Very Nice days in rain and wind of April and May. June is the start of the Hot days.
You can ride a cycle parts of 12 months a year.
Lived here 84 years and would never move anywhere else.

From the old school, nothing like looking at an original restoration job. Takes your mind back to the days when the Car, Truck, or Cycle was out there to drive or ride as original look and operation. Today, as parts are getting harder to find and other things get the restoration going toward as called in cars, street rod status.
Every one has their own mind set on what they want in owning a classic. In the car and truck industry, two big sets of organizations going. The pure restoration and the more usable restoration of using modern parts to put the vehicle on the road more like todays cars and trucks.
For me, I prefer to have something that I value as original status even if I do not put it on the road daily to drive or ride.
It is just what you want in your cycle or car, leave it as original as possible and thus have
not destroyed the original body or frame or cut and add to satisfy your ownership of the cycle or car.
Its your own cycle, car or truck so have it as you want it and remember, you bought it, not anyone who complains about the restoration.

Mike the number on my engine is M23065B.
Thanks PD, Mike, Rick for all the info. Hope to get this
engine running soon.
Is there any other number for the mag bearing other than the
5203 zz number.

Phelon on the M and Wico on the H.
The H has a set screw to keep the bearing from turning or moving in or out.
This is the first M that I have worked on and it seems a lot diff.
Anything go between the bearing and the belt pulley?
Thanks

Do you have the thickness size of the bearing that sets in the Mag plate on the M engine. Bearing is on the crank and just back of the point breaker cam. This bearing is thicker than the bearing for the H engine. Or better than that, the bearing number.
Thanks for your time.

The Frame is a 40's model. Is there a serial number on the frame to get the year status. It has everything 40's except the engine that came with it and not installed. Has a regular 40's clutch and foot pedal for clutch.
I also have a automatic clutch that came with the engine that needs bearings and putting back together. I have no diagram for the automatic clutch to see how it goes back and how it would hook up if I used it instead of the standard 40's clutch.
The carb on the M engine is different from my carb on the 46 I have also.
More than likely if I can just install the engine, I would use the 40's clutch anyway. The engine also does not have a Wico mag.
Thanks
