Carpet bagger I see your a fellow Iowa member. What part of the great state are you from? I'm from NW Iowa.

Carpetbagger and 129Richard....
Just a thought....

Either one of you considered attending the upcoming Heritage Park show at Forrest City next month? June 18-20. Feature this year is Lawn and garden tractor equipment in addition to the usual steam equipment

Or the Annual Threshermen show at Albert City Aug 13-15
Feature this year is IH and Iowa IH Collectors Club Chapter #5 is guest.
I hope to make both shows this year.

I'll maybe have to check those shows out. I have fuel, spark and compression. What's the procedure for setting timing?

Setting the static timing is easy. Check the manual in the links in the documentation section.

Back at it
 

So I now have gotten back to the 129 after a long winter. I believe I have the voltage regulator wired correctly and the new OEM ignition switch installed. The tractor now starts and runs but.....only when you hold the key in the start position. if you let the key return to the run condition it just kills.

The Ignition Switch is NOT wired correctly. Wire the switch, per the OEM Diagram, as found in our Technical Library Section, on page #5.

Tried switching wiring around on ignition switch...nothing happened when turning key. Switched wiring back and had same results. Justfor giggles I tried another switch from parts store and I get same results....engine starts and will run but only with key in start position?

You do have a Wiring Diagram right ?? And the tractor is wired exactly as the diagram ??

:bigthink:

What is the part number of your new ignition switch? Don't look it up in the parts book! Look for it on your invoice, the switch or the packaging in which it came.

Thanks!

Don't just switch wires around or you're going to have a bigger problem than what you started with (like a ruined wiring harness). The starting system is quite simple IF you are working with the correct parts to start with. As noted , triple check that you've got the right switch and let us know what you have.


We can go from there!
