Hello all Sachs Moped owners.
Received a 1980 Columbia Commuter in 1983 with 350 mile on it, I put 35 miles then stored in basement for last 15 years. The basement flooded twice to 24 inches during that time.
Naturally it wouldn't start, took to local cycle shop, he took the head off and said engine insides and gas tank too rusty to work repair, bought it home and decided to work on it myself.
It didn't have any spark, took cover off magneto and found the cam that points work off of was rusty holding points in open postion, took some Gum Out rust remover/lube, placed tiny drop on cam, turned magneto a couple turns to spread it, next day took 6" or so long spark plug file and scraped as much rust off ,around the cam.
Also took carburator apart and soaked overnite to clean it, next day took air-gun and blowed it out and reassembled it.
Gas tank was also rusty, so I built me a new one out of a 2 quart TupperWare liquid container, they have a super tight leak proof lid, drilled small hole in bottom of container, cut off about 3 inches of a Paper Mater ball point pen for out let, took a nut and screwed on to it and a plastic washer, took some black silicone adhesive sealant on it, pushed through hole. Took hot melt glue gun and sealed on outside. Set aside for 24 hours while black sealant cured.
Then I made a cradle with three 1" by 3" pieces of wood. Drilled 1 3/8" hole to insert old tank filler spout through, then secured with several 8" bungee cords purchased at Walmarts.
Laid TupperWare tank onto cradle, had gotten some cup hooks and put on side of cradle and then secured tank.
Put in new spark plug, in a cup or of fresh mixed gas/oil, let set overnight to check for leaks, next day, no leaks. Hopped on moped, peddled about 20 feet and by-gosh, it started and runs fine once I got needle valve adjusted properly when it warmed up. Will try to send pictures when I figure out how to do it.
