CS-400 MAINTENANCE

IMPORTANT NOTE - Time intervals shown are maximum. Actual use and your

experience will determine the frequency of required maintenance.

MAINTENANCE PROCEDURE NOTES:

(1) Low evaporative fuel tanks DO NOT require regular maintenance to maintain

emission integrity.

* Replacement is recommended based on the finding of damage or wear during

inspection.

Carburetor Adjustment

Every unit is run at the factory and the

carburetor is set in compliance with

Emission Regulations. In addition, the

carburetor is equipped with “H” (High

Speed) and “L” (Low Speed) needle

adjustment limiters that prevent settings

outside acceptable limits.

Engine Break-In

New engines must be operated a minimum duration of two tanks of fuel break-in

before carburetor adjustments can be made. During the break-in period your

engine performance will increase and exhaust emissions will stabilize. Idle

speed can be adjusted as required.
