Hey Paul,
I'm going to start disassembling my 20B  tomorrow, so if the rotor housings
are OK, I want to send them to you for  P-Porting, sealing plates w/ SS
tubes, etc.   Hopefully I will  know for sure within a couple of days,
provided
I am able to split  the e-shaft without a huge ordeal.

As I plan to take on another 20B  project, I was remembering back to the
last one I rebuilt about 7 years  ago.  Back then, there was a "metering
pump"
available from  someone that allowed us to inject 2 cycle oil from an
external tank (like a  boat) so that we wouldn't have to mix.  Do you know
if
that is  still available from someone?

That was Richard  Sohn.

Richard's device  works very well but if it were me I would mix because
Mazda used silly
small nylon lines on the oil squirter's and they get old, brittle and  fail.
If it were me I would have made them out of steel brake line  tubing.
Also the oil injector one way air sucking valves fail. There are a  lot of
old rotary
engines in junk yards due to failed oil injection lines.  Mixing it
distributes the oil
better in the rotor housings. Several years  worth of RX8 engines died
young due to not
enough apex seal  oil.

Thanks Paul,
All valid points......that's why you're the Master!!   So is  everyone just
using a block off plate at the metering pump and plugging the  holes where
the oil injector lines connected to the rotor housings?
Don

I would. If you have the engine apart I would take the drive shaft
out as well. No point of having that in there spinning around doing
nothing.
