Abstract
A utility engine air-to-fuel ratio control method in which during an initial or early part of a period of engine continuous operation its stability of operation is determined and if sufficiently stable a test of the air-to-fuel ratio of the air-fuel mixture supplied to the engine is performed and if need be changed to a new air-to-fuel ratio supplied to the engine during the remainder of the period of engine continuous operation. If the engine operation is not sufficiently stable the test is not started or if started is aborted.
