1967 Yachtwin 3hp, folding leg model purchased two weeks ago. I know nothing of its history, other than it won't run, and it appears someone tried to rebuild it. When I first got it home, I set it up over a barrel and got it to fire, it did not run very strong, but it did run. It didn?t pump any water so I stopped.
Next weekend I replaced the impeller and tried to start again, got only a weak response, it would sort of run with drill spinning it, but could not sustain itself.
Today I set points using the VOM, first with the throttle lever at WOT, got nothing, discovered that the points just open as the piston starts to go down
It appeared to be timing too retarded, so I redid the points with the throttle in the stop position.all to the left. With this setting it will almost run. With the drill spinning it will go along firing but it still seems that the spark is happening too late. I checked the piston travel and the points open just at the piston reaches TDC, not while it is still in compression stroke. The plugs were warm when I pulled them after this latest failed attempt to start.
It appears that someone previously did a rebuild, everything is clean and new, I only needed to replace the float and the impeller. The person I bought it from bought it non working and passed it on w/o making any efforts to get it going.
It really seems that the timing needs to advance a bit more. Beside using the VOM I set the points at .020, and even .030 to no avail. Is there some other way to advance the timing a few degrees that I, being a complete outboard noobee, am unaware of?
Thanks for your help
