Frank Acampora wrote this on 7.2.2013, but I am just now confronted with the choice of whether to invest $$$ in rejuvenating my 1977 Sailor 250, which was used only occasionally in 1980, then winterized and stored until recently. After renewing carb innards, fuel & water pumps I find it will not start, and observe very weak spark on both cylinders... Referring to the Chrysler Service Manual {8/79) doesn't help much for doing charge & ignition coil output tests, because it wants me to use: "Trigger Pulse Detector" and" C.D. Ignition Tester",...The SELOC on Johnson/Evinrudes, available from the library, is much more helpful for finding work-arounds, so I just ordered the Chrysler version from amazon, used. But here's my question, is it worth it to try to find and invest &100s in bringing this thing back to life, or should I just offer the corpse for parting out? I dont yet see a viable way to convert it (1977, Mo.: 100HA) back to points/condenser, and I read that the CDI 155-3301 is both/either unreliable/unavailable. I would very much prefer to go with the opinion of someone with experience, who doesn't have something to sell....thanks much for your interest and opinions.
