3 Redstones

[Cryertool]

This seems to be the only site with any info on these engines. I ordered 3 from China in 2012 and they have been in storage since then. I thought it might be time to put them to work. They are surprisingly big and heavy for a single cylinder engine.

@cryertool.
Big and heavy.....too right!
I helped a friend get one into service several years ago. His particular engine had a lot of casting sand in it. More than most listeroids. It was easy to disassemble and reassemble. That engine did not have any kind of breather, so tended to push oil out of the mating surfaces. I believe he made up some kind of arrangement to alleviate this issue, but have not seen the modification or learned if it works well.
It's has been in occasional service over the past 10 years. used for power outages.
Most interested in your project as well!
Cheers
