Greetings.

Can someone tell me the function of the plastic gear with the little fins or
tabs on it that is driven by the crankshaft on the eu2000 generator engine?
I suspect that it provides lubrication by splashing the oil upwards but the
part is refered to as a "governor gear."

Right not I have one with a broken gear and it suddenly started running
poorly. My first eu2000 (I'm on number 2) had a broken gear and the engine
started smoking and losing power and the oil turned black quickly
immediately after the gear broke. I have it in an authorized Honda repair
place right now and they are telling me there is nothing wrong with the
generator but I know the gear is broken--it can be seen through the oil
fill/drain hole. Since it's still under warranty, and if the gear is part
of the lubrication system then I figure Honda owes me a new engine.

Thanks.
