cleaning every 6 months is required. Cleaning includes rebuild kits.
Air Filter (Picture G)
1. Close choke (Cold Start Position). This prevents dirt from entering the carburettor throat when the air filter is removed. Brush accumulated dirt from the
air cleaner area.
2. Remove the air cleaner cover. Clean and inspect the element for damage If element is fuel soaked and very dirty, replace.
3. If element can be cleaned and reused, be certain it:
- Still fits the cavity in the air cleaner cover.
- Is installed with the original side out.
Spark Plug (Picture H)
Remove spark plug, and check for fouling, worn and rounded center electrode. Clean the plug or replace with a new one. DO NOT sand blast to clean.
Remaining sand will damage engine. Adjust spark plug gap by bending outer electrode. Tighten spark plug to (145-155) kg/cm.
