Usually the front airbox cover has a factory decal which shows the max timing degrees. The timing may be different between a regular 150 engine and a 150S engine. Check the model number on the serial plate.

The factory decal is not there any more but there is an "s" at the end of the serial number. I have been trying to figure out what that s was for.

So where would I go from here?
