Re: Yamaha Engine Stalls While Idling
When you replaced the plugs did you replace them with the correct ones. Your engine may or may not have had the correct ones in there to begin with. Check your manual. Did you gap them according to the manual specs? Changing the gap changes the ignition timing as well as the quality of the spark and may have slowed your idle speed to below the minimum. It is also possible to get a bad plug right out of the box.<br /><br />I would suggest you check the gap and heat range of your plugs. Then you may if necessary just need to increase your idle speed by the method described in your manual. Some engines use timing, some use carbs, and some use the throttle cables. If that doesn't work you may need to adjust the mixture on the carbs. If that doesn't work it may be time for a carb rebuild.
