How do I figure timing on an RE motor.

Okay so I am swapping in a 2 rotor cosmo engine into my FC.
The motor was assembled and I picked it up. It's now in my car.
But now I need to reinstall the front pulleys....
Well how do I know what rotation to install it at to assure the proper timing read.
There are 4 bolts, 10mm, on the main pulley.
We failed to make any markings on the motor before the pulleys were removed.
So now what??

there is 2 groved marks in the pulley... very tiny and hard to see, but theyre there, get a small paintbrush or something and paint the 2 grooves. and now you have timing marks. it shouldnt matter where the marks are when you install the pulley, as you have to adjust timing when its all put together anyway

I agree....but how do I tell which way is the right way???




Mat thanx for the info about painting the timing marks but I already know about that. It was probably one of the firt things I learned to do on a rotary engine....

If you get all the bolts in, then its the right way. It will not bolt up any other way... You might get one or 2 screws in but the rest wont align.

Cause one of the four bolts is offset by 15-degrees.
So the pulley(s) only fit one way.
