Docteur Solex

Bob Cordon Champ

La Vie de la Moto for June 1st carried an article about Claude Dedecker, a Solex specialist.  In between the story were a few hints and tips, translated freely:

To put a Solex engine back into running order is not as easy as it appears.  Get the manual (Available, in English, from the NACC library), read it thoroughly and take care.  Don't attempt to dismantle a Solex without adequate tools (illustrated in the manual) since to dismantle the flywheel ignition system without the special tool can result in irreparable damage.  Above all, do not ever try to simply lever it off.
When the engine is down, always change rings, gaskets & bearings, as well as the pump diaphragm, since these parts are easy to get.  Beware of thinking that another fuel pump will fit; there are over twenty different types.  Always clean and oil threads so that bolts can screw in easily by hand at first go - the threads, particularly in the crankcase, are easily damaged.  The cycle parts are very strong and easily repaired, it is the engine that is easy to damage and expensive to repair.
Best of all is to check over the machine regularly, tightening nuts and screws, particularly the sliding assembly for the engine.  The exhaust - which must be cleaned frequently, pipe and silencer - is normally the reason for a Solex to lose power!

Claude's shop and workshop is at 5, Grande Place, 59246 Mons-en-Peuelle (Nord département, D954, due south of Pont à Marcq).

LVM, which has cyclemotors in almost every issue, is available by subscription from La Vie de la Moto, BP19, 77302 Fontainbleau, France.  You need to read French, of course.
