started engine after sitting a few yrs, new pump diaphragm and gaskets, primed up it fired on second try. after warm up, it was idling at 1500 rpm, should be around 700-800, throttle plates closed, choke plates wide open, tower shaft adjustment left where it was adjusted last time it ran, no obstructions in the card linkage, only thing I noticed was the fancy see thru fuel filter was installed backwards, and it was not very full of fuel, usually is about half full running, would starving for fuel make engine idle high? Seemed like it was running fine, sounded real good.
