Getting ready for first engine run, sprayed LPS-1 into the cylinders, left the plugs out, turned the prop by hand a couple of revs and hit the starter. Loud slam, airplane jumped a bit, the prop turned maybe a degree or two and that's it. Tried it a couple more times with same result except that once the prop turned about half a turn. Checked all teeth in the starter and ring gear, no apparent damage. Checked all wiring and connections, all per the manual.
Anybody have a similar experience? The effect is quite loud and startling, I'm hoping nothing got damaged.
