My MH 50 quit running. Any ideas?

[coss]

My MH 50 (identical to a MF) has the Continental Z134 engine that has always started and run like a Swiss watch.

Recently, it started right up, ran for about 10 secs, and then stopped running and would not restart. I disconnected the gas and air lines, both of which have good flow. It turns over strongly but won't catch.

The only other recent glitch occurred after I accidently left the key on and drained the battery, and now the battery won't stay charged. The wiring is old looking and probably original.

Does anyone have a diagnosis and recommended treatment for this sick patient? I need to start bush hogging so I'm hoping for a rapid recovery.

Thanks to all.

Probably ignition coil, distributor and/or voltage regulator problem. Check all spark plug wires including the wire between the ignition coil and the distributor.

Good luck.

For the benefit of others who end up with this same problem, I thought I'd post the diagnosis and treatment.

As it turns out, I burned out the points when I left the key on. Although there are multiple on-line sources of tune up kits, my local NAPA had everything in stock and at a good price.

After a new set of points, condenser, rotor and spark plugs, the tractor is back to starting on the first turn of the starter motor,and running strong.

The longer I own this tractor, the better I like the design and utility of the 35/135 and 50/150 series machines. They are simple, easy to fix, and cheap to keep running.
