can someone with a OMC 3.8 tell me the range of the timing on tab mine is too rusty to tell was trying to check timing yesterday i'm thinking it should go form 4atdc to 12btdc or even picture would help engine is a 1981.
I found it needed to know which indentation was for 10 degrees, mine was set at 12 degrees so i'll retime it this week. and paint white mark for future. thanks for reply.
