Timing 12 degrees advanced, can't change it...

[dan ritchie]

I've got the CAS all the way clockwise, but the timing is still about 12 degrees advanced. When I started the car, it ran ok, and when I timed it, and it ended up being over 20 BTDC.

I'd like to be at about 5-7, but I don't know what the problem is.

Someone suggested that the cams might be off a tooth or two, but I checked alignment many times between replacing the belt and starting the engine, I'll try to check it tomorrow but I'm not looking forward to getting back under there if anyone else has any other suggestions.

-Did you ground the ECU when you check the timing? you'll get different reading between grounded vs unground ECU.

yep, ecu is grounded

What's your Idle Speed?

Off and on I've had some surge, hovers just over 1k, but typically is right at 700. I checked timing just a day after it started, so maybe it was up over 1,000 when I checked timing. I didn't even think about it until now...

Thanks, I'll get back to you
