Probably just some dry leaves ignited by hot engine but I’ve been using the the chipper a lot in the ten months I’ve had it so time for service. Problem is, not many folks work on small engines these days. (I’m told most push lawn mowers are considered “throw away” because it’s difficult to find parts are anyone to work on them.) I think I found a guy but won’t know until he gets a look at the chipper engine.

Getting it up from the woods was easier than I expected but getting it into the back of the pickup would have been impossible (for me) without the winch.
The hiking trail is nearly complete (more to follow) but still need the chipper for dead cedar limbs and such.
