AVS2 carb tuning. Anyone with experience out there?

You can disconnect the pump shot lever and just drive the car on the transfer circuit and as long as you don't open the throttle too fast the car will drive fine. As a matter of fact if it doesn't drive fine on the T-slot you need to address that first before you cover the issue with a bigger pumpshot. Get the T slot working right and it will require less pump shot.

Yes I had the t slot dialed in the smaller carb I had on engine before had no bog until I swapped the 650 Avs . I’m not talking about the pump shot I’m talking about the squirt nozzle in the carb under the horn, with my 650 Avs until I upgraded that the carbs bog went away. You can adjust the pump shot as much as you want but that stock squirt nozzle is way too small to supply any kind of fuel at WOT. This is from my personal experience.
