Well, actually every engine produces smoke after a rapid throttle movement. All engines incorporate an acceleration pump into its carburettor. Does not matter if it is a Float type or an Pressure Injection type carburettor. The Acceleration pump incorporated into the carburettors, discharge a brief quantity of Rich fuel mixture to compensate the rapid increase in carburettor pressure after a rapid throttle movement, which will take place faster than the mixture metering can keep up with, so this is for all engines. If it is a spit or a piper cup it actually does not matter, but bigger engines need more juice :wink: So than this mod may be fitted for all aircraft.
