valve shafts.

3. That the needle valve (L) and its lever (M) are

not worn (see gure 33).

4. That the fuel screen (U) is whole and clean

(see gure 33).

5. That the tips of the high (V) and low jet screws

(W) are not damaged (see gure 34).

6. That the intake manifold (R2) is undamaged

(see gure 33).

7. The carburettor has an extra air shutter con-

nected in parallel with the ordinary throttle

valve.
