Adjusting Deceleration Switch

 NOTE;
Correct adjustment is very important,if switch is mis adjusted, engine
may surge, or cut out during driving.

Then on the next page it sez;

"Full enrichment switch supplies the ECU with information to increase
the amount of fuel at full throttle"

If either one of these two switches are not set on the money, the engine
will continue operating the way it is now.
