2011 Grizz 700 running problems – Solved!

I had a hard time starting and keeping it running after it sat most of the summer. Fuel had Stabel in it so I didn’t think it was that. A mouse made a little home under the front cover and chewed on the wires I installed for the winch hook-up. Fortunately, that’s all it chewed on. I now leave the cover off when storing (with a little poison nearby).

I did a little research on this site and read a good number of posts saying to change the plug. I ordered a new spark plug and changed it out. It now fires right up and runs great. What’s up with these plugs just going bad. The old plug looked pretty normal with no excessive wear on the electrode. It was the original with about 87 hours on it. I’m just happy it was only an $8 fix.
