Chris - since you have the electronic whizbang, have you upgraded to an alternator?

We have had lots of customers with "carburetor idle issues" and a ew with no alternator. The generator does not provide a significantly stable voltage at idle. Generally, the problem (running rich) goes away when the engine gets above maybe a 1000 RPM.
