The timing is set by adjusting the link rods inside the engine.Setting the timing on the Johnson outboard should take around an hour.emove the trigger link rod socket from the ball stud by hand. Remove the socket from the ball stud and decrease the length of the link rod to increase the timing, or increase the length of the link rod to decrease timing speed.

The venting system, or plumbing vents, consists of a number of pipes leading from waste pipes to the outdoors, usually through the roof. Vents provide a means to release sewer gases outside instead of inside the house.t the building drain system's lowest point, the drain-waste vent is attached, and rises (usually inside a wall) to and out of the roof. Waste exits from the building through the building's main drain and flows through a sewage line, which leads to a septic system or a public sewer.
Direct-venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort.
