Take a look a the far left most nipple. That's where it goes.

That's why I suggested a piston compression tester. You can either buy one for $30-40 or borrow/rent one. Just have a friend come over for 30 minutes to give you a hand with the test.

 

thanks a lot for the info
my buddy is gonna come over on the weekend with a compression tester and we are gonna see if my motor is pooped

 

I actually just tested my engine with a piston compression tester. I got 3 even bounces of 60 psi while holding down the release valve on both rotors. According to rotaryresurrection.com I should have seen around 35 PSI, so how accurate is that information really?

I also only got a peak hold of 90 psi.

I guess as long as you see some kind of consistancy in each compression chamber, you can kind of judge you motor's health, like majik said.

 

To be honest, I'm not sure what Kevin is checking exactly with his steps. I only use a piston compression tester to basically check the variance between the rotor faces and the variance between both rotors as a whole.
