I took my 1816 to the shop for a little attention. I was never happy with the factory engine mounting, and the fact that to replace a belt the engine had to be removed. I know it was only four little bolts, but I spent hours trying to get those fine thread bolts started. The shop added a steel plate which allows mounting bolts to be accessed from the top. It can also be slid an inch or so which will allow for belt replacement in a matter of minutes.
