The new vacuum gauge arrived from JEGS. It was waiting in the mailbox when I returned from yesterday's road trip.
The first thing I adjusted was the fuel levels on the bowls. I had thought that the mid-point of the sight plugs was where they should have been set, but after talking with my buddy Ray, I was told that I'd be better off with the fuel levels at the bottom edge of the plugs.
I used the vacuum gauge to adjust the idle mixture screws. I had questioned whether or not they were set correctly because they were only around 1/4 turn out from seated. My highest vacuum was achieved very close to that setting.
Next I re-adjusted my timing. This time it read around 24' @ 850 RPM. Why it read so different from the last time I'd read it, I don't know. So, I bumped the timing back to around 14'. I had felt that it cranked a little hard after the engine was warmed up and wanted to try retarding it anyway.
I am hearing a very slight exhaust 'tic' from the driver side header. I believe it's from the spot that we'd welded up before. It's barely perceptible. - But we'll have to re-check the weld. The location is behind the steering gear and can't be seen. I think that rather than pull the header off I'll remove the steering box if we have to re-weld.
Well, it's time to give it a test drive. I don't want to make any further adjustments until I see how it's running now. My fingers are crossed.
