Re: Small block home tune

so, I fitted this engine into my LI series 3 bitsa, did a couple of short local rides, 1 mile, 5 mile, 10 miles. Then, i rode it the fairly short journey of about 20 miles to the WWSC rally in sunderland. It really is lovely to ride: easy starter, flexible and pretty nippy.
BUT, on the way home this morning, it very suddenly cut out. It felt ignitiony, but wasn't.

the failure mode is obvious, what isn't so obvious to me is the reason for it. piston bore clearance was 4 thou. ring gap was good. But I've obviously done something wrong, but what?
