TF727 part throttle shift points

I think I found what the problem is.

The arc between the Holley carb and the factory TV lever is off.

We need to drill a new hole closer to the pivot point to match the throw of the Holley carb.

I had played with the geometry before, but attempted to modify it at the carb side, and I obviously did it wrong. Lol.

I’m planing on trying this tomorrow or Wednesday and will report back with results.

But from what I’m reading it’s exactly what’s causing our symptoms.
