I've seen pictures of various Poulan Engines - Some have mounting lugs on the side like normal RC engines, and some (like mine) don't. I made my own mount from an aluminum push plate (the kind on doors where you push to open) from the local home renovations store. I don't have pictures of it, but it looks very much like this one:



I trimmed the back cover plate to match the engine profile, then placed the mounting plate over top and drilled the holes to match. I then replaced the bolts with ones which were 1/4 inch longer and went right through the mount and cover plate, into the engine casing.
