I want to congratulate Team Orion and Ryan Cavalieri on YET ANOTHER major race win. Pudge was on a mission in Arizona and won the Nitro Challenge Expert Buggy final in convincing fashion. This is a testament to the quality and reliability of the Team Orion Alpha ABI CRF line of engines, running flawlessly for all of qualifying and the 45 minute A main. Great job guys.

I think you can attribute the reliability and consistent tune to the new aluminum body carburetors, they're fantastic.
The inserts for the new carbs are here:
