Fig. 15. Knight Valve-Timing Marks—4-Cylinder
To check up on the timing, back the flywheel up an inch or two and insert a thin piece of tissue paper into the exhaust port and turn the engine in the running direction until the paper is pinched, which signifies that the valve is closed. The marks on the flywheel, timing gears, and the crank case should be in alignment. [Fig. 16] shows a diagram of the timing marks on the eight cylinder Knight engine. The method of timing this engine is as follows: (1) Turn the engine over until the marks I-4-R-H—D-C align with the marks on the crank case. (2) Turn the eccentric shaft and sprocket until the arrows shown in [Fig. 16] are in line with the guide marks on the front end of the chain housing. Then put on the chain and check up the timing, using the thin piece of tissue paper.
