If you define running without complete engine rotation, then yes, technically speaking, it's running, what a fascinating piece of machinery.
I once roll started my old diesel landcruiser backwards, did it rattle. Had 4 reverse and one forward gears . Fastest toyota in the world but only when going backwards.We have a 2 cylinder 1950 tractor and it sounds very similar to that when it runs but its a 4 stroke. It sounds so awsome !!I look at these old tractors and think what troubles did they have when it got stuck down in mud Some of the Transition between Forward rotating engine and backwards is so smooth that it seems the operator was just doing a gear change!!Had a James Sports Captain 125 in the 60's that you could slow the tick over till it almost stopped and it would quitely back fire then run backwards! The look on peoples faces when you wheel spun off backwards was priceless! I don't know much about engines but my Yamaha Blaster broke it's woodruff key without me knowing and I managed to kickstart it and it started up and ran backwards. It also threw the pedal back up violently and smashed my knee into the handlebar which hurt like a bish. Very cool. I was a bit scared when he got off and walked away with it running. I get this is a restored but retired tractor i. e. the tires look brand new The mini 110 case model is awsome id love to meet that guy or id love to have his drive to do that of corse im shoure the man has small tool shop that has every thing i knew a few guys like him and they have every thing in their shop
