i'm curious if someone can explain to me how the new "electronic" needle and seat works. i have taken the bowl off when cleaning the carb. it appears the flow of gas is controlled by an electrically actuated plunger instead of the old style needle/seat/float that i am familiar with. these seemed to show up about the time CARB compliance started and the EPA was mandating cleaner engines.
i'm wondering what actuates this device and what the failure mode is.
i'm wondering if it could spontaneously shut off the flow of gas into the carb for a few seconds of if a spring internally might be broken or loose.
i think it is only sold as part of the carb so that might mean a new carb anyway, but i would still like to try to understand how these new fangled things work ;-)
