1. Make sure carb is closing to appropriate gap quickly (not closing slowly).
2. LSN (low speed needle) is a bit lean.
I have modified several of these and the racers that are running them (on race tune) with 9853 & 9901 pipes are getting 10.5-11min. I raced with a Paloma (modded) when it first came available. I paired it with a 9901/ 41020 and got 12min on race tune. Track was semi tight with high traction.
