1810 magneto/ ignition module

[onnie]

Hi all,
Ater chasing down what I thought was a fuel problem on my 1810(1400 hrs) it now looks like I've facing a failed magneto instead. I know this is a lot of work (that miserable shroud) so I'm trying to decide if I want to tackle this or not. This isn't my primary tractor, but it is used on areas of my property where my Kubota isn't practical, maintaining trails up a large hill and other mowing etc. That and I love this model, it's my second one. Your thoughts , tips, advice are welcomed. Thanks in advance.

First off make sure its the magneto not just a kill switch or wiring.
I hate to see people load up a parts cannon and blast away installing "NEW" parts that are defective right out of the box.
Its not a difficult job to remove the engine on them to get to the flywheel shroud.

I 100% guarantee you will find the coil packed solidly with Debris and the cooling fins,and the stator under the flywheel.
Most times it is the killing factor of these ign magnetos and engines.
While the engine is out, one can address any oil leaks, also blow out under the flywheel.
Also you can check the rag joints/driveshaft conditions as after 40 years they do need some attention unlike todays mowers that require no militance, because in 7-10 years you just sell them to scrap to be recycled.

Thanks George. I know you are correct about debris buildup as I saw it and blew out what I could when installing a new fuel pump. I still would have to pull engine to check kill wire, so even though the OEM magneto is expensive i would probably do it. I thought I'd also pull the starter and have it rebuilt, maybe new head gaskets, etc.

You can actually fish around a bit and at least find your kill wire without
removing the engine, I think, it's been a while. White wire I believe.
Pulling these engines is not quite as daunting as it seems at a glance.
If one just takes his time and enjoys the ride it can actually be pretty cool.
If you are physically able to do the work, go for it.

Here is assuming you have the M-18 in it.

Thanks for the response and especially the pics. I have pulled one before, but I was 41. My first 1810 caught fire somehow and it was a lot of rewiring and replacing of different things to get her going again. Now,67 years old, a much better mechanic, but with rheumatoid arthritis in the hands and fingers . I think I'm gonna do it. I guess I start with the tin at the nose cone so I can get the bolts that get grill off ? And yes , same engine, Mag 18. Thanks again, keep the tips coming, lol!
