cam timing default for sohc(1990240sx) engines?????

Im planning on buying a timing light so that I can find out where my timing is set at the moment. What is the default timing for the ka24e engines and up to how many degrees can I adjust it???

You mean Ign. Timing?

Stock is 15deg BTDC.

If you run 91 octane you can bump it to 18 no further…
