Well, I fired the Leo .40 up today, after cobbling together a test stand and then bolting it to a handy lump of angle iron in the garden that used to be part of a garden gate.
I stripped the motor down prior to running it and gave it a good once over. I gotta say, I was well impressed. The castings are very smooth, with no hint of porosity, inside or out, and the machining is also top notch. Inside was clean too with no swarf or any rough edges. Ports were accurate and very well milled. Tolerances were absolutely spot on, the piston is tight in the bore but not too tight and all the bearings were snug as a bug.
I used a thirty year old spinner off my old Enya, together my equally old German electric starter and a new 10*6 prop. Fired up first go using a #8 plug. Taking it easy (and a bit rich) till it's run in, but it revs like the clappers and idles well too.
This is a nice motor and a bargain at $55 or so from HobbyKing.
What goes up...better bloody stay up (until I say otherwise).
