Listen to Lynn,

 

I once left my rotary sit for approx six weeks as I converted over to Tracy Crooks Ec2.  The oil had been washed out of the engine by the failure of my HALTECH aftermarket EFI which failed with the injectors fully open.  Gasoline poured out exhaust pipes.  I had the intake manifold off for some modifications – in any case, when I attempted to start the engine with my new EC2 – there was NO compression, Nada!  I spent a week poking through the exhaust port to loosen five of the six seals – but, nothing would cause the sixth one to budge.  Had to take the engine off and tear it down and even then broke the sixth seal trying to take it out.

 

Apparently with the six weeks of humid summer weather and little/no oil on the seals – a light coat of oxidation formed and caused the seals to stick.

I now go out and start my engine about every 2-3 weeks.  If a longer period I pour some light oil down the spark plug hole and rotate the engine by hand a couple of times.

 

Lynn knows of what he speaks as I can personally attest.

Jerry, things are real quiet on your part, how is your project coming??  We do miss your activity like when you where on the Tailwind Activities.  My project is receiving the finishing touches and will be ready to go when the snow clears in the spring.  It is looking like I don't have enough prop (68 x 72) on the Rotary, will need to get it out of the garage after the new year and run it some more with the tach that Bob White put together for me.  Farmer John

 

The rotary has ports open to the outside all of the time. Humid air can enter the engine as it goes through heating and cooling each day. In a barn, in a hanger, even a heated shop. I use motor oil in the intake and turn over the engine a complete cycle, (three crank revolutions) and tape the exhaust pipe shut. Turn over three revs monthly when out of service.

 

More of them have died sitting still than running.
