Several years ago I replaced the lost brass NPT drain plug on the engine block (just below the cylinder head) on my 1954 Elgin 7-1/2hp engine. However I recently noted on another engine that the drain plug had a drain hole in it and really isn't a "plug" but a drain. Do all of the West Bend Elgin engines have a drain plug like this? If so, I guess I'll have to drill a hole in it but it doesn't seem to make sense to me. I've used this engine with the solid plug for several years.
