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.
