Air and Fuel Systems Check
When diagnosing a low power problem first troubleshoot
the air and fuel systems to make sure the engine is
receiving adequate intake air and fuel.
Check the intake air system for leaks. Make sure a
sealant is used on the through-hole capscrews which
secure manifold cover to the head.
Check the fuel system for correct timing and fuel
delivery.
Valve Adjustment Check
Verify that the valves are adjusted correctly (refer to
page 5-197).
