On My Repair Manual It Says , Spark Plug Rv-15yc (champion) Spark Plug Gap For Magnum ** Vertical** Twins Mv18 Kohler Gap To 0.025 , For **horizontal** Magnum Twins Gap 0.0035

On typical gasoline lawnmower engines, the gap can be anywhere between .020" and .035"

Gap should be set at .030

Yes, go on Google and lookup your lawnmower and then on the site ask for spark plug type and check gap size.

Make sure it is the correct spark plug with the correct gap. Then check to ensure that fuel is being delivered and is not bad

Most 6 HP for that BS is 0.30

How old is the engine? Does it have electronic ignition or points? Check the engine stop wire where it attaches to the throttle control on the engine. Make sure it is not grounding out. Has the magneto been removed? That is the Y shaped part behind the flywheel, where the spak plug wire attaches. If the mag has benn removed, it needs to be re-adjusted. The correct gap is .020 of an inch, about the thickness of a matchbook. This gap is measured between the two legs of the mag and the flywheel. I hope this helps, good luck.

No difference in gap, just resistor plug does'nt interfere with radios,tv,electronic equipment

The gap should be about .010 (Ten Thousandths of an inch), but truthfully, the way I set it is to loosen the coil bolts and place a shiny business card in between the coil and flywheel. Tighten the coil up snug against the business card and then remove it. This should set the gap close enough to the correct setting for you; done. Hope this helps and best of luck to you.
