Does anyone know what the timing should be set at for these 2 engines? Another problem that I am having is the 85 will charge the battiers slowly with what seems like a trickle charge, not a full 12 amps. When I run the engines with the lights and depth finder on for about 4 hours it will drain the battier down far enough to stop the engine. Oh yeah, the 1977 idles ruff.<br />Thanks Smack.
