Help wanted for 1958 Falcon 81

Post  trophy on Sat Sep 08, 2018 6:52 pm

Bought recently as a box of bits. Engine sorted but need advice on a few other things:-
1) The carburettor body has no model number, only "Villiers", then "shaw" encased inside a diamond shape. Throat size is 24mm. Throttle slide is Number 3. Choke slide WDC 1. 120 main jet. Jet needle 3 & 1/2. No marking on the pilot jet. Float chamber stamped Mk 111. Air filter is a V.1800B. Is this set-up suitable for the bike?
2) I fitted new rear wheel bearings and stupidly didn't note which way the spindle came out. Only noticed that one end is slightly longer than the other. Can anyone confirm which side does the longer end go to? The manuals are no help.
3) Any recommendations on tyres? Has the front to be ribbed?
4) Both brakes need re-lining. Who would you send them to?
5) One of the footrests has been butchered, anyone got a pair I can purchase?
6) Also need a 48T rear wheel sprocket. Who would stock these, the club maybe?
All (any) replies appreciated.
Ride safe all.

1 carb should be a S25 Villiers early ones had no number stamped on them 120 main jet and 3 1/2 slide are correct for a 10E, the nedle should be set 1.95" out from the bottom of the flat surface of the carb ( may need adjusting for wear to get optimum position)
2 if you have it in the wrong way your sprockets will not align, put it in the wheel and put the wheel in the frame if it aligns it is ok , if not change it round, from memory i think the long side is to the opposite of the sprocket? but it has been a while
3 your choice
4 Villiers service will reline your brake shoes
