2.33 Speed Adjustment
The speed of the engine is controlled by the tension of the
speeder spring which is internally attached to the speed control.
The control has two adjustable screws which are adjusted
and locked to give the rated full on-load or variable speed as
determined by the engine build.
Fixed Speed Adjustment
The two screws are adjusted and locked against the speed
control lever to give the full on-load speed. The right hand
side adjusting screw (A) increases the speed when it is turned
clockwise.

2.33 SPEED ADJUSTMENT
The speed of the engine is controlled by the tension
of the speeder spring which is internally attached to
the speed control. The control has two adjustable
screws which are adjusted and locked to give the
rated full on-load or variable speed as determined
by the engine Build.
Fixed Speed Adjustment
The two screws are adjusted and locked against the
speed control lever to give the full on-load speed.
The right hand side adjusting screw (A) increases
the speed when it is turned clockwise.
Figure 2.33.1 Fixed Speed Adjustment
Variable Speed Adjustment
The speed of the engine is controlled by the tension
of the speeder spring which is internally attached
to the speed control which in turn can be operated
either by a cable or rod.
The idling speed must not be set below 850r/min.
1.Move the speed control until it is against the
adjusting screw (A).
2.Turn the adjusting screw (A) anti-clockwise until
it has no further effect on reducing the engine
speed.
3.Turn (A) clockwise until the no-load speed is
850r/min.
The adjuster can be turned further clockwise if a
higher idling speed is required.
Figure 2.33.2 Variable Speed Adjustment
4.Tighten the locknut.
5.Move the speed control until it is against the
adjusting screw (B).
If the speed is not correct turn the adjusting
screw (B) clockwise to reduce the speed and
anti-clockwise to increase it.
2.34 THE ENGINE CONTROLS
The Engine Control
The control knob, spindle and plate assembly was
modified on and after the following TS engines:
35 01203 TS1
35 06483 TS2
35 05021 TS3
On later TS and all TR and TX engines the knob
and spindle are one assembly and the location
plate is a separate item.
Note:
The current assembly cannot be used with an
early type of unmodified locating plate.
Removing the Assembly
1.Remove the gear end cover.
2.Remove No.1 cylinder fuel pump inspection
door.
3.Move the automatic excess fuel lever (B) along
the shaft towards the outside of the crankcase
and hold it in this position.
4.Remove the small dowel pin (C).
Figure 2.34.1 Engine Control
5.Remove the spring (D) from its location on the
excess fuel lever.
6.Remove the excess fuel lever assembly (B) and
spring (E) while withdrawing the control lever (F)
and plate assembly (G).
7.Examine and renew the '0' ring (H) if necessary.
8.Replace the cam spring (A), if removed, to the
lever assembly (B).
9.Replace the control lever (F) and plate assembly
(G) through the crankcase into the spring (E) and
