how t find top dead center?

[Barebones]

Prepping my '48 Cub, Barebones, for the Mid-Michigan Old Gas Tractor Association show next week (featuring Internationals this year) and was temporarily stumped with wires and firing order as part of a tune up.

My tractor has a magneto and the rotor it uses has plastic gears that seem to be able to be positioned anywhere on the shaft, as opposed to the type that fits only one way. Well...I didn't pay attention when removing the rotor for replacement and needed some guidance. George Willer's post did the trick. Simple enough I could follow it and got the machine up and screaming once again by easily finding top dead center. Plus, another post led me to install the wires in correct order on the new American-made cap.

Many thanks for such a valuable resource.

When I reviewed the bill for parts bought down the road at Alderman's, I was somewhat surprised at the total. The killer: $40 for the rotor! Yow!

Anyway, mission accomplished.

Should have driven another mile down the road (same side) and picked up a rotor at Steiner.
They aren't a site sponsor, but have some pretty decent reproduction parts. I think the Magneto Rotor is still the same price though.

Yep, mag rotors ain’t cheap
