I have a Montgomery Ward riding lawn mower with a PTO shaft driven roto-tiller attachment. It is a 16 Twin 656 cc. Model 33420.. I am trying to finding service manual(s) so I can rebuild it. The engine runs but the wiring has been cut spliced and or removed.

I believe mtd made these.. what brand engine? Briggs?

The complete information on the engine is:
Mdl-4014 type-0128 01 code-77122012

The complete model is: Gil 33420 A This leads me to believe it may have been manufactured by Gilson!!

I also know that Simplicity built some of the same Ward mowers.

I think that I will be able to use any one of the mentioned wire skematics to rewire switches, lights, starter, etc..,. Do you have any leads?

Briggs
Made in 77 so it more then likely has points unless converted...
I have a wiring diagram pdf specifically for briggs
