Subject: Matchless '28 350cc SV
Hi Jean, with my knowledge you should have with the Matchless T/4 1928 a
carburetor: two level semi-automatic with pilot jet to give easy starting
and slow riding, as the B&B, type 121 either 123 with Main Jet 90, pilot
jet 16 and needle extension 1,50" with 121 type and none of 123 type. 121
type with the throttle dia. 15/16" and choke bore ,78" with the 121 type and
0,65" with 123 type. If I am not wrong the121 type should be yours.
Send your address and I shall post you more information on it.
Can you pass the # s of the engine and frame? Just for the record -
Peux-tu comme il me le demande me donner les N° de cadre et moteur pour leurs archives ??
Merci d'avance
