I have a 7mm insert and that I believe helped bump up the fuel mileage.
Not even a gallon on the motor yet and it runs great but do these motors have that point where they change and open up? I know the last 2 motors I had(not argus),after a gallon or so,they wake up and I had to retune them? Someone joked that with most motors,they reach the point around a gallon when 'their balls drop' and they reach their full potential.
Yes she will run rich once it drop it nut. My .23 that was lapped had did that in mid race on me around the gallon mark. So if it was not lapped it might take just a little longer.. nice place over at clarks not an easy place to run at with the locals there. They are pretty quick ant they. I think that is the nicest track I ever been to.
