How to you find the compression stroke? I've tried to start my car with both sides and still no start. So i figured it was my cps. also does anyone know how to adjust the cps? I consulted the tsrm and it didn't help. I lined up the drill hole to the notch. I'Ve also tried adjusting it up and down and still no start.
Compression stroke/How to adjust cps?
- Thread starter TooRandom
- Start date
Well i've done that. If you turn it once 360degrees around it'll be at tdc and when you do another 360 it becomes the opposite with the marks at 180. But i don't know what side is the compression stroke. Thats what i'm having trouble with. I've tried both sides and it doesn't start.

I pull the cover to be exact, uh also I usually do all that before the motor is in, but if you do it with it in, that's fine too I had to go to a friend house the other day and do it for him, thank god I remembered off the top of my head to do it... lol
So what you're saying that if the cam lobe point is facing upwards so i can see it and the crank is at 0 degrees it'll be at tdc on the compression stroke? Or i put the cps in when the lobe is up?

/\/\ gud question, i need to know this to.
Not to jack the thread, this link shows that the Cps Drilled marked needs to be aligned with the Groove, if thats not set right, can it make the car miss fire a little ?

I also hate to hijack this thread but when i look through the oil filler port the nose of the cam lobe is behind the shelf, unlike the drawing in the TSRM. Any ideas?
Take out the #1 spark plug, insert 1 foot long small diameter wooden dowel in hole, turn crank damper until wooden dowel is at max height. You are now at TDC. Cam pulley index should be a "zero"...crank damper index should be at "zero".
Installed correctly, the CPS should look like this:

Thank you, JDub. All looks right but still runs like crap. I will keep looking it over and see if i missed a vac. hose somewhere. So much to remember on this car.
You still have to set timing after doing this! Just base timing here 
For the initial drive, I turned the CPS by 'feel' (where the engine starts sounding like it should), Drive until you get to full operating temp, jumper the diag box, then set timing with a timing light

i'd love to if it didn't stall when i depress the accellerator. I calibrated the TPS already, just checked all my hoses.
