Just lengthen the pull rod to the carb a bit until you like the way the trans upshifts. There is a singular lack of rocket science involved. Besides, that is likely all that got changed when the carb was taken off.

Could be the linkage adjustment but don't forget on original Ultras there is no downshift as such because for normal driving trans starts and stays in high range. If car is below a certain speed it drops out of direct drive into high range converter for the extra burst of speed but that feature is locked out if going over 45-50 mph. Manual says if going over 50 but after so many years that given speed can be different due to linkage adj, different tires, speedo gear, etc etc.

Not to be too critical but those still look grooved in your "after" picture. Any reason why you didn't turn them nearly smooth?

I polished the commutator again after clearing out the grooves. I don't have a lathe, so I'm just using fine sandpaper. That's not going to take down the ridges that have been worn into it by the brushes. If you're talking about the grooves with the mica, I'm pretty sure those grooves are supposed to be there. They were pretty obviously there before.

Yes, of course there are the grooves between the contacts. I meant the circumferential grooving/wear. What I do is just stick it in a drill chuck then use a sanding sponge, that tends to get it pretty darn good without the need for a lathe. Just a suggestion. 🙂
