Your idle speed should be about 800-900 rpms. ![]() But that's correct isn't it? I've got HP pump there and when it was running before the timing was adjusted it was 75PSI. I'm assuming that's because it was running at 1000 vs 1200 RPM. Oh yeah I forgot to add that when I finally got the timing right the oil pressure dropped from 75PSI to about 30-35PSI. But I checked the timing again after I tightened the screw and it's still dead on 10. And you can smell it on your clothes while out there adjusting. I can feel the fumes, it burns my eyes a little. One veteran mechanic told me to not mess with it and let it run a little lean or rich I can't remember what he said, but he says if you changed it right away it might melt a piston. One thing I'm noticing is the carb has a lot of smoke coming out of it after you shut it off. I sat there and turned out the curb idle screw but it never changed the idle. I have the air cleaner hose port on the back of carb plugged up while the air cleaner is off. I have the air cleaner off because there's no way to get to the curb idle screw on the Thermoquad with the air cleaner on. You can tell it's still idling a little on the high side. ![]() It's still idling a little higher than it should at about 1000-1100. Ok I went out and followed what you said RapidRobert and I got it perfectly aligned with 10BTC. It's confusing because in the "Setting Initial Timing" instruction you're doing the same thing except first youre suppose to turn the knob to a certain number. ![]() The 1st instruction is to "Turn the Advance knob to desired degrees advance setting." So do I leave the knob still at 35-36 and turn the distributor until the white mark I painted on the damper is aligned with 0? Or do I turn the knob back to 0 and aligned the paint mark with 10? I'm assuming this "moving mark" they're telling me to observe in the "Measuring Initial Timing" was the one the strobe light was making. So what does that mean? The next step in the instructions with the timing light are a little confusing. Then I shut the car off and looked at where I had turned the knob to and it was 35-36. I held down the button, Viewed the Marks, and turned it until the moving mark was aligned with the 0 on the tab. Ok I read the instructions again with the timing light and I did the "Measuring Initial Timing" Procedure. Re: Understanding how to use Advance Timing Light Why would I want to put it back at 0? Or do I just turn the knob to 10 and follow the instructions and turn the dist. Then it says to tighten the bolt back up. After selecting the desired Advance it says to press and hold down the button, view timing marks. But what am I suppose to do with this Advance knob. So I was going to put it at 10 BTC and see how it ran. The spec is 7.5 +/- 2.5 degrees, so basically 10 Before Top Center. And that's what I was going to do being it's all built back stock. I can sit there and set the timing to exactly what the specs are but that's about it. It tells me for setting initial timing to "Turn knob to desired degree advance setting." I don't really know what that means. It has a knob on it you turn for Advance it goes from 0-60. ![]() I'm following the instructions with the timing light. I have this Advance timing light that I'm not really familiar with. I tried to turn out the idle screw to adjust it but it didn't even really change. I got scared running that high on a new motor eventhough the cam break is done. It's idling way too high, like maybe 1200RPM in Park. I let it run a few seconds and zapped the throttle to let off the fast idle.
