Thanks to Fred et al,
Fred, I followed your tips printed 01/24/01, reviving a 1976 Cimatti City Bike
with a Minerelli motor. So far so good. Thanks also to the unknown soul who scanned a schematic of this motor, and carburator and made it available.
My comments: guitar strings (electric or acoustic high "e" strings make excellent pokers for clearing gunk from carburator passages). Cost about a dollar at a music store.
I removed the "pin hole" screw right above the carburator float
to get the damn thing working first time a around. It started great a couple of times, but, a week later, the spark plug was soaked, so I knew it was flooded. I put the screw back in, and, magically, it worked.
I am using an old water bottle fit with a piece of toilet tubing, aircraft clamp, and plain old 1/4" tubing from Lowes as fuel line. This is because my tank is rusted and I am soaking it in de-ruster.
My question for anyone is: how tight do I make my chain? It is sort of adjustable by loosening the axle nuts and moving a little lever.
Also, at local motorcycle stores, I can't find an in line fuel filter to fit inside 1/4" diameter fuel line.
