6-4 Limiter Cap Removal/ Installation
Tool
The limiter cap tool (carburetor maintenance tool:
848-8W9-0080) is used for limiter cap
installation/removal.
Removal
Insert the limiter cap tool extraction tool's threading
(M2 counterclockwise threading) into the idling
limiter's hole and screw it counterclockwise while
giving pressure.
When it is firmly threaded, pull the limiter cap.
If it is difficult to screw in the limiter cap tool,
firmly press the tool while screwing. When
threads are completely meshed, pull it out in
one stroke. If cap is damaged and stays in
the hole, use a pick type tool to remove it.
Installation
Insert a new limiter cap in the low speed mixture
needle hole. Press the cap deeply into low speed
mixture needle hole to prevent tampering.
Be sure to install only a new limiter cap.
The limiter cap is a very small part. Pay
attention not to lose it.
