Model # 917.25511
Serial # 2272
Decided to fire this up and no spark so I thought I would check points. I don't know squat about small engines and was expecting to find traditional points. Any help or direction to PDF manual. Thanks

So, what you've got there is a CDI (Capacitor Discharge Ignition).  They've got everything except the ignition coil mounted where you expected to find points.

 

The way the CDI system works is the charge coil (lower left in your 2nd. picture) charges a capacitor to 30-50 volts, then the capacitor is discharged into the coil which boosts the voltage to fire the plug.

 

I found a little diagnostic information HERE.  He sort of tells how to repair the CDI but it isn't very detailed.

 

The CDI itself is part number 610759 and is no longer available.  The coil is part number 610760 and is also discontinued.  There is a complete ignition replacement kit available HERE for $125.  The replacement kit is an automotive type ignition and will not work with the standard key switch.  You need to add a switch to turn it on and off or get a suitable key switch.

Make sure you have a good spark plug.

Since you have flywheel off, check the white wire coming from stator going up to the module, make sure there is no chaffing or breaks int he wire, this can ground our module.

Next, there will be a ire coming from the ignition switch to the stator or the module, that is the shut off wire or grounding wire. Make sure it's not broken or rubbing and grounding out on frame. If you can, unplug this wire, then check again for spark ( requires putting everything back together) Sometimes the witch goes bad and grounds out the module when in run position.

If still not spark, then your module is probably burnt up.

Dale's conversio is not a bad price, but you will have to make sure you have a good charging system since it runs off the battery.

so I poured gas into carb and as video shows...Wait, wait, wait for it

Yes wiring needs some attention and I have to figure out what model engine I have. Does not seem to be a tag to identify model., or not that I have found. Mind you I had overlooked the on/off switch since dragging this tractor home from scrapyard 2 years ago

Now that I know my $70 tractor runs and drives it time to spruce it up. Sandblasted and painted wheels, they were very rough.

The tractors runs amazing. Everything is painted but don't want to assemble grill until I figure out why throttle does not respond. Thinking geometry wrong?? Nothing is siezed. Any thoughts? There just seems to be something missing that throttle cable has no effect on that speed control.  Thinking there is a small part missing on top of carb??

I will find a manual for engine possibly to download

   In your second picture the shaft to the left is the throttle butterfly shaft. it is connected to the governor by a wire linkage. looking at the geometry of the system it appears to be a straight line between where the linkage attaches and the butterfly shaft. at this point it appears that no matter how hard the governor pulls on the linkage the shaft will not turn any further. To increase engine speed the throttle shaft must turn counter clockwise in your picture. to slow the engine the shaft would turn clockwise. when the control plate hits the screw directly to the right of the throttle shaft the engine should be at idle. By gently moving the governor lever at the other end of the linkage wire you should be able to turn the throttle shaft 1/4 turn from idle to full open. A picture of the plate on the throttle shaft at a more straight down angle would help identify the problem. Don

I didn't notice until secondtry mentioned it, the arm of the governor connected to the buttery fly plate is at an angle from the lower mount and the rod is at an angle, mine is straight up and down and my rod is level to that governor arm. Maybe someone rigged it up on yours.

Also, my governor spring is in the outside hole, yours is in the inside hole.
