I have a Lister FR-1 on a heavy steel generator base that I picked up a few months back. I've decided I'm not going to need the engine. This would be suitable for about a 4Kw genset.
I also have another FR-1 on a similar base. This one *may* be missing a few parts, but there is also a box of spares including what may be a new piston and rod.
Engines are located in Vancouver BC at present. If you're not afraid of doing a bit of restoration work, these are the best and last of the Cold Start series engines.
It's nice to have a complete unit to refer to when taking apart and putting together and the buyer could always restore both and sell one to recoup costs + That's what I would do if I had the time!
$800 for the pair. Sorry I have no photos yet.
