i have a 1985 150 mariner, and i read a thread the other day that said to remove the spark advance module. if i do how do i need to set my timing, please let me know in detail if you can, and let me know if this is good advice or not. this engine somtimes is hard to start, at times it seems to flood and other times it seems to be starving for fuel, i was wandering if this might be a bad advance module.
