Mahle tells me it might be Husqvarna?
Looks like someone May have cut a squish band into it. Maybe just the lighting. What do the ports look like?
Round flange for intake or flat with two bolt holes?
Well when I was in school we were taught the metric system and fractions. Then in industry most is standard with some bastardized metric stuff so we are thoroughly confused. For example if you give me the outside temp in Fahrenheit I don’t know what you are saying. If you say your engine temp in Celsius means nothing to me
Wasn`t metric, we were still using A.S. back then but now have both systems to deal with, my tool boxes doubled in size . Still prefer A.S. sizing but have adapted to metric somewhat.
