Finally got a good test run of the twin today. The tune is close enough to see A/F ratios in the ballpark- 4.8 to 5.4 with a throttle hit. No unusual vibration or shaking. So I'll start re-installing it, shooting for the July event in Loring.
Strange- how the exhaust doesn't sound like a twin, just sounds mean like the four did! And totally unlike my odd-firing John Deere.

Neat tractor. The very first time I let out a clutch pedal, I popped a wheelie. I was about 6 years old, dad was standing on the "drawbar" of the 1951 MT his dad bought new, and he told me to let out the clutch. I sure did! lol He almost fell off, and quickly taught me the proper way to release.

Your build is well beyond neat, I enjoy glancing at the updates.

I'll also forego the Harvest event at Loring (just a week away). Without a way to put the engine under load I can't be confident of proper A/F ratio in each cylinder. On top of that, the FAST air/fuel ratio meter readings have gotten flaky.
