Warm up the engine up to the working temperature. At full supply of fuel measure the frequency of rotation of a bent shaft, without exceeding this mode more than on 5 pages. At discrepancy of the frequency of rotation demanded break a plastic cap of the screw 1 (see fig. 3.37
), weaken a lock-nut and establish by this screw the necessary frequency of rotation of a bent shaft. Tighten a lock-nut and establish a new cap.
