Automatic decompression

Correction is required in the following cases: - If the collar pan constantly engages the cog lightly, in the case of running the engine and zero position of the decompression lever (Shaft moves back and forth)

In this case, shorten the tappet somewhat and dimension “A” will become larger (see figure)

- The decompression shaft is not rotated further properly from position “2” of the handle

In this case, lengthen the tappet somewhat and dimension “A” will become smaller (see figure)

Correct the position of the collar pan to the cog (lateral distance) by a small movement of the rocker arm shaft on the cylinder head plane.

NOTE

Choose distance “B” so that certain functioning of the automatic system is ensured. In the running position of the engine (lever position “0”) the collar pan may not touch the cog.

Fix the cog segment on to the shaft so that the cogged area is on the upper side when the flattened part of the shaft points upward.
