Very nice balsaman. Very neat. It would probably run more smoothly with a flywheel although it's pretty smooth anyway.
Runs quite slowly, it it a long stroke? is that why it's called the lazy v4?!
Yeah what sort of valve gear is it balsaman? From the first pic it looks like there are two holes for piston type valves in the block. How are they driven and are the exhaust ports on the outer sides of the block??
Thanks, great engine ..
