1920 needing a little trouble shooting

Recommended Posts

Alltractoredup

I just picked up a very nice Duetz 1920 with 60" deck and 46" snow blow for cheap. The issue:

Motor runs but there is something electrical for sure. Has the M20 motor. Front lights flicker....and when I pull off one of the plug wires it dies. I put it back on, start it, pull opposite side and dies. Both sides die just as if turning key off.

Question: shouldn't motor continue running even if on cylinder has no spark? Is this some sort of ignition protection?

What am I missing

I am not sure of the issue, but I do not believe it has anything to do with any kind of ignition protection. They usually will continue to run on one cylinder, albeit poorly, obviously. You state it kills like you shut the key off? That seems quite odd.

I am probably wrong again

But thought I read once you need both plug wires hooked up to get spark

And they both spark at same time

Even though one is on compression stroke and the othe on exhaust stroke

In the kohler manual I downloaded for my 1920 with a ch20 it says in the "test for spark" section...Do not crank engine or perform tests with 1 spark plug lead disconnected and not grounded, or permanent system damage may occur.

Not saying any thing about your methods mind you cause I probably would do the same, but might not be good with the electronic ignition and such. Try putting a good spark plug in the plug wire and ground it to the head and see if it will run that way...might be interesting!

This may be true for the Commands, but I think this a Magnum? And I have had issues with running in the past and have pulled plug wires to determine the bad egg and the Magnums continued to run with one plug wire pulled. These were Sunstars and one Sovereign.

Well I think I got it, Checked spark plug on one side and it was stripped and slightly cockeyed in cylinder head.....thanks previous owner. I can't complain I only paid $400 for entire package

Snow blower does have that silage plow look...LOL

Previous owner bought all new bearing and never got back to it so I have all parts and new bearings!!!

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
