I just picked up this little beauty a few days ago for $50.00 and have plans to restore it as best to my capabilities to mow my back lawn. Any info would be great, from what I have learnt so far in the forum it seems to be a mid 70's change over twin rail with a Kirby engine. It was listed as a non goer but on Inspection I noticed the throttle cable is broken at the handlebar end where it connects to the throttle leaver, so I assume it's an easy fix. Everything else looks pretty good besides the paint and a service, but I'm not familiar with the Kirby engine I have read that they weren't as good as the Briggs and having plenty of knowledge with Briggs Aswell as 3x 60102 2hp engines ready to go should I replace the Kirby or should I keep the deck matched with the original engine, what's everyone's opinion in re-birthing the engine the one I want to use is a 1979 60102 will it still be classed as original or does it mess up the space time continual.
