I noticed something about my SA 200 that I found a little odd. The fan blows air through the radiator rather than pulling it through and blowing it over the engine. That's counter to (I think) every engine I've seen. Maybe I just didn't notice on some of the big pumps and stuff. I was going to use the side table to do some welding, and thought the blow from the fan would be a problem. Then I fired it up and found out it blows the air the other direction.
When I rebuilt this, I didn't take the fan off, nor any of the pulleys. So this is the way it came or someone else before me changed it. Everything seems to run fine, just seems a little odd.
