New 13b first start. with Loud BOOM. Timing question
 
OK First off i swear i timed it the right way. But its a new engine. And I cant keep fooling with it unless i am sure the timing is correct.. because it went BANG. so maybe it was Flooded. But im not sure..

When i put the engine together i rotated the #1 rotor to tdc. With Front mark on crank pointing to the timeing marks. i then took the cas and lined up the dot to the Left black thingy. I know in this photo its not Lined up. but that was after i turned it over. If i dont have a mirror and the engine is in the car, what is the best way to make sure the rotor is in the correct location? thanks. in advance.

I never tried it on a rotary but with bikes I always stick a screw driver down the spark plug whole, and rock the engine back and forth until the screw driver gets to its highest point. Ill try this tomoro in my car and report back lol.

you are off... you want the pulley on the yellow mark, and the CAS to look like this

Remove the flat black cover on top of the CAS held with two screws.

Look at the rotor of the CAS and how it has two *pointers* on its top area.

Then look at my attached jpg. The pointers should be cutting across the corners of the square looking, black, reluctors. IF so, then the CAS is installed right. IF not, then unlock the CAS and rotate it til the pointers cut across the corners of the black reluctors.

And or read this thread if needed: https://www.rx7club.com/showthread.p...=CAS+TOP+COVER

Make sure to follow break in procedure. Here is a good guideline ---->http://www.rotaryresurrection.com/2n...p_breakin.html

i thought the two pointers in the cas had to be lined up to the middle of the black pieces?
na turbo s4 and s5 all have different main front pulleys?

Nope. If you'll just pull your CAS out. Then line up the marks on the BOTTOM of the CAS gear/cas body.......then hold that positon and look at the top of the CAS (cover off of course), you'll see that the two "pointers" will be positioned just like the picture BEEFHOLE posted up above several posts ago.

The "pointers" will be seen as cutting across the CORNERS of the two black reluctors inside the CAS, not the center of the reluctors.
