Solex S 3800

Η Solex ήταν Γαλλική εταιρεία κατασκευαστής καρμπυρατέρ και του μοτοποδήλατου Velosolex.
Τα καρμπυρατέρ Solex χρησιμοποιήθηκαν από πολλές κορυφαίες Ευρωπαϊκές μάρκες αυτοκινήτων, όπως η Rolls -Royce, Porsche, Volkswagen και η Mercedes Benz. Είχαν, επίσης, άδεια  με την ιαπωνική εταιρεία κατασκευής Mikuni να τα διαθέτουν στην Toyota, Suzuki, Yamaha, και αλλού.

Ας έρθουμε όμως στο θέμα μας κι ας δούμε αυτό το μοναδικό ποδήλατο με μηχανή.
Η Velosolex έχει ένα κινητήρα 49 cc (3,0 cu in) τοποθετημένο πάνω από τον μπροστινό τροχό. Η ισχύς παρέχεται μέσω ενός μικρού κεραμικού κυλίνδρου που περιστρέφεται άμεσα στο μπροστινό τροχό από την τριβή του ελαστικού.


Το πρώτο πρωτότυπο μιας Velosolex δημιουργήθηκε το 1941 και χρησιμοποιήθηκε τακτικά στα πλαίσια ποδηλάτων, όπως αυτές με την επωνυμία "Alcyon» και ήταν τροφοδοτούμενα από ένα 45 cc (2,7 cu in) κινητήρα που αναπτύχθηκε από την Solex. Τα Velosolex παρήχθησαν στο εμπόριο και άρχισαν να πωλούνται ξεκινώντας το 1946 με κινητήρα 45 cc, χωρίς συμπλέκτη, στη συνέχεια, αργότερα με ένα κινητήρα 49 cc. Η Solex, αν και δεν είχε ποικιλία πολύ από τη μία έκδοση στην επόμενη, πούλησε αρκετά από  αυτά τα μοντέλα:

Παρακάτω θα δείτε αναλυτικά τα τεχνικά χαρακτηριστικά του (για όποιον ενδιαφέρεται), όπως κι ένα βίντεο.

Fuel Mixture / Ratio Information

3%
33:1
- In a clean, separate container, thoroughly mix 4 ounces of two-stroke oil
  with 1 gallon of regular 87 Octane unleaded gasoline.
- I recommend Castrol 2T, 2-stroke (2-Cycle) engine oil

* Never add oil directly to the Solex fuel tank.
* Mix your fuel in a clean, separate container.

                                          G - "Rupture" mark
                                          H - Lighting connection
                                           I - Ignition coil - Points connection
                                           J - Ignition coil - spark plug wire connection

~ Ignition check - see: Owner's Handbook, page 3
~ Fuel supply check - see Owner's Handbook, page 3
                                              
~Ignition Points / Points Gap: 
The ignition points must be adjusted so that they just begin to open when the "RUPTURE" marks on the flywheel (rotor) and engine (G in above photo) line up, rotating the flywheel (rotor) clockwise. There is no set points gap on a Solex engine. The amount that the points open is not relevant. 

~ Flywheel Puller
- Do not use a standard two - , three - , or four - jaw puller to remove the flywheel (rotor). 
- Use a puller that makes use of the three M6 tapped holes in the flywheel (rotor).

S 3300 USA - No Spark:
1. Install a NEW spark plug...not almost new, good as new, only used once, etc. NEW, NEW, NEW.
(See Spark plug and Spark plug gap above for correct spark plug type and gap.) 
*Check for spark by carefully holding threaded portion of spark plug against cylinder head and spinning flywheel clockwise, looking and listening for a blue spark to crack across the spark plug gap.
See:  Video; checking for spark
 An orange/yellow spark is no good. Feeling a jolt while holding the end of the spark plug wire means nothing. 
2. still no spark...install a new spark plug wire. Be sure that the end of the spark plug wire has a good clean connection against the tab on the back of the ignition coil. (J in above photo)  
Check for spark as above*. 
3. still no spark...remove flywheel (rotor) using special Solex flywheel puller (see: Flywheel Pullerabove); clean the points (D in above photo) (search online for instructions on cleaning ignition points). Disconnect the ignition coil from the points (I in above photo) and test the points for continuity when closed, no continuity when open. Reconnect the coil wire (I in above photo). Install flywheel. Adjust the points as described above under ~Ignition Points / Points Gap....Check for spark*. 
4. still no spark...install new condenser (C in above photo), check for spark* 
5. still no spark...install new ignition coil (A in above photo), check for spark* 
6....install new flywheel. 
(On a Solex, the flywheel key is part of the flywheel casting. The key fits into the keyway slot on the crankshaft to correctly position the flywheel on the crankshaft. You must verify that the flywheel key has not been sheared off.)
