450 carb on 440BB

[zip69_1999]

I have installed the 450r carb with ZRPilots adapter, great help, with the following:

Pilot: k48
Main: k180
Needle: Middle
A/F: 2.5 turns

Super torque on mid range and high end, but....

Problem: bogs a little when at dead stop and snap throttle, in gear, and pops a little on decel. Other than that, this is an amazing upgrade.

1)Bump up the pilot to a 50 or 52 then re-adjust the A/F screw
2)move the needle to the 4th down from the top
