I just want to pass along a helpful hint I received from my local Snapper repair shop. I have a 2006 Snapper HiVac with a BS Intek 6.75. When I purchased the mower the previous owner stated it would not start when hot which is what I experienced the first year. I heard this was typical and bought the mower anyway for fall leaf mulching (BTW with gator blade is great). Always stated first or second pull when cold and runs great.

I really like the mower so I called my local dealer to see if there was possibly an engine swap or to purchase a new commercial model. He stated he had fixed this problem several times with a new spark plug model RC12YC gapped at 25-28 vs. 30-32. I purchased this plug It was gapped at 32 out of the box. I reduced the gap to 26. Used today for the first time and it started first pull when hot several times. Thought I would pass this hint along.
