1960 Other Mercury Models firing order

Looking for an old book in the basement and I found the darn thing. Lucky you late as this is. This is an old motor manual and this is the firing order that it states. Firing order= 1R-1L-4R-4L-2L-3R-3L-2R timing is4 degrees BTDC. If you need any other data send me a private message. I'll help you with what I can.
