Setting Base timing for exhuast cam retarded one tooth

[dragrush]

Need to set base timing for an exhaust cam that is retarded one tooth. When using a timing light do I still try to get the damper notch to 5?

you may try...

but you may find the damper notch/mark will not steady on one location...

Why are you attempting to set ignition timing when mechanical timing is wrong?

Why are you attempting to set ignition timing when mechanical timing is wrong?

It's a temporary fix until I can get the cam gears aligned. But for now I need to get the base timing close to correct as possible because I took off the CAS for unrelated issue. This is when I noticed the marks were not aligned.

I'm just trying to figure out if I have to make up for the offset and get it around 10 or 0 or just keep it at 5.

You're wasting you time if you're not sure the balancer is good or not. Does the car even run ok? If that cam is wrong fix it then set ignition timing.

Wait...what? Are you talking about degreeing and using adjustable cam gears, or at you talking about just setting base timing with getting the cam gear marks aligned? Huge difference.

But for now I need to get the base timing close to correct as possible because I took off the CAS for unrelated issue.

Do you have an adjustable 1g CAS or are you talking about a variety of the 2g CAS?

If a 1g CAS, then you need to install it, make sure it's not 180° out, and then set it using a timing light. You can put it in the middle of the adjustment range to get the car fired up and up to temp.

If a 2g CAS, then there's not adjustability in the ignition timing and you have a problem with the damper if it doesn't align with the T mark (car off and engine at TDC) or 5° BTDC mark (car on, engine up to temp, and using a timing light).

I have a 1g CAS. The exhaust tooth is retarded by one. Non adjustable timing gears (OEM). The crank timing is good. The car runs the way it should.

I'm just trying to figure out where to set the base timing (the notch on the damper to the timing cover) with an exhuast cam retarded one tooth (rotated counterclockwise from the intake cam)

Why is your exhaust cam gear retarded by 1 tooth?

You'd be referring to ignition timing if you're at all talking about the damper.

1 tooth doesn't equal one degree, so it's up to you if you want to set it at 5° BTDC or retard it more.

1 tooth [not equal] 1 degree. ***hint hint There are not 360 teeth on our cam gears hint hint*** Ever notice that 5* spans about 2 teeth on adjustable cam gears?
