1) One thing I quickly noticed when tearing down my 20B is that there

is not

an eccentric shaft thermo pellet in the flywheel end of the e-shaft.

Does

anyone know if this means that it was already bypassed on the 20B like

we

commonly do on the 13B?  Or, is there another system that should be

bypassed

on the 20B???  I've attached a picture of the end of my e-shaft

without the

thermo pellet.

2)  On the Turrentine video he shows removing the check balls in the

oil jets

and installing carb just instead.  Has anyone done this, and if so,

where can

you buy the jets?

3)  Does any know when the Turrentine 20B video will be available??

Thanks,
Don

The thermo pellet is there for USA emissions-enables heating up the oil
quicker. Emissions are also why the rx7s also have very high idle on
startup as well, in fact all three systems-ACV, AWS, EGR are for that.
. That is all.
Jets are from the carb makers (Holley), or from Mazdatrix or Haynes or
Racing Beat. They all sell em. Or you can make em yourself.
Let's all ask Bruce to hurry up the 20B tape, his other one was great.

 If you make a jet yourself, what diameter orifice would you use?

Chuck Dunlap

2 mm according to the Racing Beat Technical Manual and catalog on page 42 Chuck.
