Hi Max,

The engine looks very similar to mine, although the picture is a little blurry. The number of fins appear to count the same on the head and sleave.

The exhaust port looks a little different, but I think the one in the picture you sent me looks like it may have an exhaust adapter or extension on it.

The carb on mine also seems a little different and perhaps mine is a little newer model carb.

I'm enclosing two pictures, one with the same view and the other with a view of the opposite side.

What are your thoughts?

Thanks for your help.

Best regards,

Wayne
