The Wisconsin engines used a similar magneto to many other manufacturers. The pickup area and the magnets need to be rust free and the gap should be about the thickness of a business card. Also, check to see if the magneto is grounded well. If there is a separate wire going to ground, make sure it has good connection also.

Is this engine run on Magneto or coil ignition?

The 850's used an 8 1/4 HP engine, co I assume it was replaced at some point.

The contacts may be rusty behind the flywheel.
Since the magnetos for these are obsolete, many have just been bypassing the magneto and converting it to a 12v coil ignition system.
