" Hi Joe,
I'm trying to set the timing on a 1985 Johnson 120 (Model J120TXCO). As you know, it's a loop charged motor. I read a couple of other posts pertaining to timing (1987 115 and 1977 140) and am wondering if it's appropriate (with the plugs out, the ignition connected to a spark tester and the engine cranking) to retard the timing 4 degrees since the motor is equipped with a power pack. If so, I should set the timing at 17 degrees BTC since the motor calls for 21 degrees BTC running WOT. Does this sound correct? Thanks for your help! You truly are a great resource.
