Well, I know it was more than a couple days, but I'm back. Turns out the polarity was wrong, though I'm not sure why I got it wrong this time when my procedure has worked in the past, so at least I have experience for the future. However, it still only produces 17.5 volts ac, so definitely...

They all still strongly attract the tip of a screwdriver, so they definitely still have at least some magnetism.

Have a courage 24 hp that is not charging. I jb welded the flywheel magnets back on and it still wasn't charging, only about 3 to 4 volts ac at the stator end leads. Some of the magnets were slightly chipped and one was missing a significant sliver, but I would still expect it to put out more...

Also before we get too far, check that the engine just isn't overfilled with oil.

After you've run the mower for a while, getting it nice and hot, stop it and remove the dipstick. Do you see a white-ish smoke slowly coming out? This is a telltale sign of a blown head gasket, or very excessive cylinder blow-by.

Fuel goes bad much faster in a carburetor fuel system because the volatile components of gasoline in the bowl will evaporate through the bowl vent, leaving behind the heavier stuff, and eventually causing the bowl level to drop enough for a little more fuel to be left in, and the process repeats...

Can you engage the blades in reverse, stop moving, then move the key to the normal mowing position, then try backing up again and see if the clutch will kick off? That will confirm to us that the reverse switch has a proper signal to the control module.

Possibly something with the auto choke setup? Not exactly sure how the automatic choke works on this Chinese engine, but it may have to do with the governor arm position. Make sure the choke is staying wide open. A governor problem should never cause the engine to "die out". As always, a video...

Ok my bad Charlie, i wasn't aware that this engine has DSAM on it. Basically there is an spark advance computer module box on the side of the blower housing, with two separate wires, i think one is yellow and one is brown, with spade connectors that go to the spark coil. My test procedure for...

When you say "pull", do you mean you unplugged the connector? Or that you physically removed the entire switch and connector? The connector may have a shorting bar to prevent users from disconnecting the seat switch, so that the mower will always die with the parking brake off. We need more...

I thought the current standard procedure was to replace either DSAI or DSAM systems with the newer and simpler MDI system, which only requires a ground wire. https://discountonlineparts.com/lawnmower/?c=Ignition&b=Kohler&id=16691 The MDI system does not require a positive supply either. I think...

The wiring diagram for your mower is on page 31 of this manual https://www.searspartsdirect.com/manual/19cq3tfazs-000247/craftsman-917271030-front-engine-lawn-tractor-parts See the box labeled "ignition unit"? This represents your engine magneto. The body of it is grounded (represented by the...

Good idea, the only problem is idk what size tubing would work.

wow, yeah thats a big gap

If I recall correctly, the darlington transistor is "turned on" by the magnetron-branded trigger coil, and when the transistor is on, it allows current to build in the primary winding.
