Initial Inspection and Diagnostic Overview
Before diagnosing this system, all other engine associated systems that can affect
air/fuel mixture combustion efficiency or exhaust emissions should be checked first. These systems include basic
carburetor adjustments, mechanical engine operation (
spark plugs, valves springs, etc.),
ignition system, gaskets (intake manifold, carburetor or base plate) and loose vacuum hoses and fittings.
