(see Fig. K2q
To check the choke stove pipe for any blockages, carry
out the following operations.
1. Disconnect the choke stove pipe at its choke
butterfly housing connection.
2. Connect the calibrated orifice
(RH 8095) to the
open end of the choke stove pipe, then connect
a
manometer capable of measuring 25 in. (63,50 cm.) of
water level difference to the orifice.
3. Run the engine until it reaches normal operating
temperature then allow the engine to idle and observe
the depression shown on the manometer. The correct
reading should be between 16 in. and 18 in.
(40,64 cm.
and
45,72 cm.).
4. If the level is less than 16 in. (40,64 cm.), examine
the pipe and choke stove assembly, remove any
blockage. After removing the blockage, again check
the manometer reading.
