rpickle Posted April 25, 2011 Posted April 25, 2011 Just putting around the driveway (since the yard is a swamp!) on my newly revived 7016 w/16HP Briggs, trying to put some runtime on the engine, when POP!, then all quiet except for the engine free-spinning to a stop! Yikes.... Popped the hood and found the spark plug laying on top of the head. Did not notice anything was wrong with it previously. I found another plug (thankfully, because I would have NEVER been able to push this thing up hill and into the shed in this slop!) and installed it. Fired right up. This plug seemed to snug down fairly well. Should I Helicoil it or run this one for a bit to see if it will hold. The threads on the old plug were not sharp. Seems, though, that the head would strip first.
comet66 Posted April 26, 2011 Posted April 26, 2011 Are you sure the plug was properly torqued to begin with?
427435 Posted April 26, 2011 Posted April 26, 2011 I wouldn't mess around with a helicoil unless it happens again. Check the plug torque after a few hours-----if it's still tight, forget about it.
Brettw Posted April 26, 2011 Posted April 26, 2011 Happened to a 7114 Kohler I brought home. Ran it for about 15 minutes and popped out the plug. Put it back in, torqued it down, never had another issue (with the plug popping out).
rpickle Posted April 26, 2011 Author Posted April 26, 2011 The original plug would not torque down after popping out. wWeird since I had pulled it a few days earlier to check for spark. When I reinstalled, it seemed to tighten up w/o issue. The new plug torqued down solidly. I'll keep an eye on it. Rick
