I've always been told to start your sled at least once a month during the summer. Well I wasn't around much, and I don't think it got started at all. I was thinking of starting it this weekend. Is that a bad idea, or if so, should I do something like clean out the bowls? It probably won't see snow for a couple of months or so. I like and miss the smell of them. Oh, its a 98' Formula Z 670.
