Spud Miller's Cave / Re: jet change for nitro

With regard to a carburetor requiring a jet change you need to remember the sheer weight of Nitro compared to alky. Your fuel is fed into the engine by a pressure differential between the booster and atmospheric pressure, this does not change because the fuel changes therefore you need to increase jet size to get the correct volume of fuel. All that fuel has inertia and Nitro has more inertia than methanol is another way of looking at it.
