anyone know where I can get one or how much they are?

the rotary specific one?

rotary specific ones are 1640$ available at mazdatrix, lol

pay the 100$ and have it check or get a normal one a try to read without the checkvalve

speaking of mazdatrix i would like to vent a little.

dealers say "oh u need this part? we dont know wtf it is, is this it?" and the give you some random shit thats not close to what you want even though you give them part numbers and tell them what it looks like.
once they find it they say okay we found it now bend over and spread your cheeks you owe us $5000 for this part that you could get in a junkyard for 600.

mazdatrix is like okay we got all the parts and we're not assholes like the dealer but we'll still ask you to spread your cheeks to pay $2500 for this part you could find in the junkyard for 600.

damn.

yea mazdatrix can be kind of a rip off sometimes

but the reason I ask is because I found an S4 TII in a junkyard with a decent body, door won't close cause the latch or something is broken, interior is pretty nasty, the guy says it runs but I'm not even sure yet... anyways I want to check the compression before I even think about picking it up, even though I'd just end up selling it anyway.

You could do the poor mans test and just check for 3 pulses on each rotor when you crank over using your hand. Otherwise a normal compression tester works you just have to remove the check valve.

what about for a 12a 1982? do you have to remove the checkvalve still, and if so, wheres it at?

the valve (if there is one) is gonna be in the flexible tubing that comes with the tester, on the 'spark plug' end. You have to remove it if there's one with a valve stem remove or a small plier. It looks like a tire valve stem.
