Sellers feedback is positive, but there was one comment: "Didn't
realize from listing that these are made to order and take some time"

So looks like you're paying the seller up front, getting the motor sometime later.

Is Expoxy still the common method for p-port insert?

In some quarters it is. I prefer the welded variety.

I have been burned a couple of times buying engines mail
order. The best way to buy an engine is either basket case
where you can inspect all the parts or a running engine in a car.

Mazda engines are not hard to assemble. One must be meticulous
when assembling the watch like seals on the rotors but the rest
of it is trivial. I would buy a junk 12A engine and practice.
Some times you can get them for free.

You can also buy engines from established builders with a long
track record such as Mazdatrix. They run every engine they build
on a test stand before they ship it. They will also dyno it for
you for an extra charge. Their engine prices are reasonable.
Perry Mick has over 550 hours on a Mazdatrix engines.
