Very happy to find this Forum. Have been a wood lover and user for many years. I just read a very good book called “Norwegian Wood” by Lars Mytting. Well worth reading by anyone who loves wood.
I was just given an older 22 ton Duerr splitter of unknown age, by someone who said “I borrowed it from my grandpa about 20 years ago. It stopped running and I got a good deal on a new splitter and don’t have time to mess with it.”
It has a 5 hp Briggs and Stratton motor. The head is aluminum. It has no spark. New plug also has no spark. I think it probably has points and condenser ignition. I haven’t been able to find the serial number on the motor.
Anybody have suggestion about where the serial number is on the motor, and/or other points of interest about B&S engines? Also am interested in comments about these Duerr beasts.

Can't help you with your splitter but agree with you about 'Norwegian Wood'. I should dig out my copy, if the wife hasn't donated it someplace, and reread it.
 
Post some pictures of the splitter and engine
 
Points, condenser, coil is the order of attack I would use on that engine.

Lots of those old beasts still out there making firewood.

You should find that serial number. It should be stamped.
 
Got the flywheel off and discovered a fractured key on the crankshaft. Also discovered the motor has no points or condenser; after a little research I found the motor has a magnetron ignition system. I am guessing ~mid 90's manufacture. Looked again for model/serial # but it still eludes me - have looked in all the likely places. Maybe one day after I stop looking it will jump out at me.
 
Here is another attempt to upload pics of the old 22 ton Duerr.

Found a few search hits that might help out
 
Yeah that motor is newer than what I had pictured in my head. I sure wouldn't go too far considering a five horse Predator from Harbor Freight isn't big money and they run well
