CARBURETTER
WITH PILOT JET SYSTEM
|
 Fig
2. |
|
Your
carburetter may be vertical, inclined or horizontal, but diagrammatically
this view applies to all models, the variation being in the
attachment to the engine and of the float chamber.

| TWO
DESIGNS |
Fig.2
is the sectioned view of the standard Amal carburetter as shown
on sheet 1, figure
1. This is the standard design where the primary air to the
main jet and the pilot jet system comes in jointly through the
main air intake, see figure 3, sheet
3. The type numbers are 274, 275, 276 and 289.
An alternative design is made where the primary air to the main
jet comes in through four visible ports around the base of the
mixing chamber, and where also the air supply to the pilot jet
system is separate. The type numbers of these carburetters are
74, 75, 76 and 89. |
These tuning instructions apply to both the above designs. |
