As far as mpg, I've not had a chance to calculate that although the previous owner said they got something amazing over 25. It was higher than that maybe because I thought it was crazy high and discounted it.
Here are some pictures of the engine, fuel system and gearbox from underneath. Maybe this set up will be familiar to some. Oil leaks, yes. Apparently the 3-53 is known for making a mess.
