Re: 4.3 mercruiser diesels
from my experience dieseling at shutoff of the engine can occur if,<br /> 1 the motor is hot <br /> 2 carbon build up on valves and combustion chamber causing glow plug effect,<br /> 3 no va***e advance at the distributor,<br /> [ either seized or not fitted ]<br /> 4 no solenoid on carb throttle to close throttles completely at engine shutoff,<br /> 5 often a combination of the above,<br /> generaly fuel still getting into the motor readily is the problem via wide throttle opening at the idle position, no va***e advance often requires wider throttle open to get suitable idle speed.
