Does this engine come with a muffler installed?
Features + Benefits says exhaust manifold not included but spec says it has a muffler. Maybe that means the muffler attaches directly to the engine???

Does this HM-80 Tecumseh engine have a power cord to run a light?
My old HM-80 motor has a wire with a plug on it that you can plug a light into. I did not see anything on the picture or literature that said it has a built in power cord to run a light?
