Re: Suzuki Idling Problems
The fact that it idles in the driveway and not the water is merely an indication that your engine isn't running right. The lack of backpressure in the driveway allows a poorly running motor to continue to tick over.<br /><br />You need to narrow down the problem which may be minor and maybe not. Is this engine new to you or have you had previous experience with it? You may want to do a compression check. If you've fried a cylinder it will never idle right.<br /><br />Pull the spark plug leads one at a time (ground the pulled plug lead) and see which cylinders aren't pulling their load (bad cylinder has no effect when pulled).<br /><br />Buy an inexpensive spark tester at an autoparts store and check the spark on all cylinders. <br /><br />Squirt some premix into the cylinders one at a time and see if it picks up. If you have spark on a cylinder and the squirt helps then you most likely have a fuel issue with that cylinder such as a carb in need of a thorough internal cleaning and rebuild.<br /><br />In order to run in the water as opposed to the driveway, you need all cylinders firing normally, the idle mixture must be set to specs (on a clean carb) and the idle speed must be set to proper rpm (~800rpm I think) in the water in gear.
