SPARK PLUGS
Remove each plug and check condition.
– Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.
– A white blistered coating indicates overheating. A black coating indicates an “over rich” fuel mixture.
Both may be caused by a clogged air cleaner or improper carburetor adjustment.
– Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are
obtained with a new plug.
– Set plug gap as specified in engine manual..
