    I was using my tthp yesterday, and it started to sputter and even quit altogether for a second, then came right back up to full speed, so I checked the plugs, and put new ones in, the old plugs didnt have any oil on them but did have a grayish white color to them, Ive never seen a plug look like this, but the new ones seemed to do the trick, as it ran fine the rest of the day, but it does still sputter a little bit but only when it is first started, runs great when mowing though? Any ideas on this? Thanks.
