Paul
I have followed you for many years and I ran into the above car last week
and bought it. Please tell me what 2 cycle oil to mix with the gas and what
to do to keep it running.

Peter  Duffecy

You lucky dog. Most that age have over 300,000 miles.

Use Walmart 2 cycle oil offered in gallon cans.

It has an injection pump so you don't need to mix oil with the fuel IF the
nylon lines are still OK.  A BIG IF.
At that age they are brittle and could crack at any moment. I would replace
them with steel brake line but that might take a lathe.

These cheap plastic lines are critical to the life of the apex seals, and
engine for that matter, if you are not mixing
2 cycle oil with the fuel.

Should I assume that the lines are bad and mix oil till I can be sure. How
can you check these and I do have a lathe available to me.
Peter Duffecy

Yes by all means that is the safest way to do it.

However they could be cracked and there could be some engine damage.
The engine may still run. It is a good idea to check the oil lines and the
compression.

Nylon oil line failure is the main cause of Rotary engine failure. If it gets apex seal
oil it will last at least to 300,000 miles and probably a lot more.

The apex seal wears very roughly  at the rate of .001" per hundred hours at full
throttle. The seals probably can tolerate .030" total wear. That would
be 3000 hours. If you put Iannetti silicon nitride seals in it you
are looking at 20,000 hours :-)
