I bought the engine used on Ebay from Ron in Virgina.

It was used for about 300 hours in a Zenith 601 before the owner pulled it to
install a slightly larger Jabiru engine.

It was shipped in a very sturdy crate by truck and I picked it up at the
trucking terminal.

I plan to install new bearings and cylinders on the engine.  I also need to
switch from the top mount starter to a bottom mount Diehl case.  The intake
will be changed, but I should be able to use the carb that came on the engine.

I will also attempt to reuse the 2-1 exhaust pipes.
