I've had a few mowers over the years with elbow pipe fittings on the exhaust outlet to redirect exhaust gases like what Norm mentioned.
Yes WCE ,I do like the orange Sunbeam mowers, I have wanted to find the 2 stroke version with no luck ,I do know someone that had the 4 stroke one and wanted $30 for it ,I may have to buy a 4 stroke Sunbeam for the front badge so I can make a 2 stroke orange Sunbeam.
Mf ,the bases are different for the 2 stroke and the 4 stroke orange Sunbeam mowers ,you can't just re drill them. The 4 stroke has a large centre hole and the 2 has the much smaller hole.
Yes the orange based Sunbeam mowers came out 4 and 2 stroke.
Here are some 2 stroke images I stole from somewhere ,not sure if someone here owns this mower.
That was a little strange finding 3 cup start and 2 side pull Victa mowers in 2 days but no mowers were found today.
