First fire up after rebuild with hot cam, modifed inlet manifold, high compression pistons, high lift rockers, upgraded valve springs and a lightened flywheel, parts supplied by Brian Fallows in the UK. Urgently need to sort out an exhaust and silencer;)

First test used stock ignition, will test using advanced and post results.

Hoping it puts out above 35 hp

Motor is going into my microlight/ultralight aircraft to replace a Rotax 447 that is too thirsty.
