2007 John Deere Gator with engine run-on [SOLVED]
We have a 2007 John Deere Gator that “diesels” when turned off on hot days, especially if the engine runs at high RPM. Adding Sea Foam to fuel is easy, but think spray may be better. Not sure where to insert tube. Any suggestions? Thanks!
Hi Rob. Both products are important for cleaning up your Gator’s issue. If your Gator continues to fire/run after the key is turned off, you have excessive carbon buildup in the chamber hemispheres that gets hot (like charcoal) and causes the fuel to ignite. Could also have a hot spot on a spark plug. I would keep the tank fuel low and regularly add a can or two of Sea Foam or High Mileage – the higher concentration will work to soften and clean the varnish/carbon buildup as you operate the Gator. Another idea is to treat the upper engine with Sea Foam Spray through the air intake – consider you’re running a whole can over the intake valves and into the chambers in a matter of 5 or so minutes. You can also remove the spark plugs when hot to spray into the chambers and let soak for a few days at a time…. Because it’s ‘dieseling’, am guessing that your Gator has a carburetor intake so just a matter of removing the air cleaner to expose the throttle valve opening into the carburetor throat. Hope this helps!
