ignition questions?
Posted by: GWLee ()

I'm working on the 60 and setting up the carbs syncing and such. Also the timing, which has led me to a question.

The 60 has two engines for 60, early and late. Mine is the late, which the book calls for the timing to be set at 4°. The timing tab has 0-4-8 and then a space then the tab ends.

I was checking the distributor points and such and it all is by book. Which the dwell is set at 32°. So I checked the number on the distributor and it has a 259 which the chart of corvair distributors says is for a late 60 engine, with automatic which matches my engine and transmission.

But my question is, when I read the specs on the 259 it says timing should be set at 13°.

So I'm now confused. The car seems to run fine at 4° but I was having some hesitation which is why I decided to check the carbs and timing and such!

So anyone have an idea! Should I just set it at 4° and leave it at that?

Also I have one rocker that keeps loosening up. I adjust it and the nut loosens up after running and driving it. I know I can take it off, the nut, and rap it with a hammer to tighten it up, or can you double nut the ones that keep getting loose. And then replace them all this winter!

Am I looking at something with the timing that isn't an issue.

If it were mine I would advance it a few degrees at a time until you get a light ping, then back it off to the last position where it didn't ping. That will get you the best mileage, power and drivability.

This post reminded me that you sent a PM and that I forgot to answer. Oops!

You asked how to set timing to the specified value when the timing tab ends at 8-degrees.

The answer is to use a set-back timing light which includes a knob. Turn the knob until the timing mark is aligned to zero on the engine's scale and read the timing off the display or knob on the timing light.

I had to set my timing into the stratosphere to eliminate the hesitation but never had any spark knock.

FWIW, there were five or so different distributors in '60 and each had it's own initial timing. The '60 manual only shows the first design.

Thanks guys. I guess I'll possibly look at upgrading my timing light or do as J.O suggested and take it up until it pings. But using the new timing light makes it easier to record and keep for later use if needed! That will help my son when he takes over the care of this car.

Thanks much hopefully this and fixing the nuts on the rocker that keeps getting loose will end my issues and I can concentrate on enjoying the car.

Craig you've mentioned getting excited about getting your first corvair done and on the road? The 60 is my first car and I've driven it some but not nearly as much as I wanted. Keep running in to things that needed fixed. But if this new engine works as good as it did, I will be set.

I hope you get it going very soon!

Thanks

Set it to 6, that's within the range of your timing tab. Then test. You can do that with your existing timing light.

Thanks Greg.
That is next, and hopefully I can check this today.

Yesterday I spent the time on the carbs and it runs a lot better. The hesitation I had was bad but now I can push on the gas and it doesn't hesitate. But if I blip the throttle it will just slightly. I'm hoping the timing correction will get this cleared up!

But it idles smoothly and such!

Spent the day working on the car and trying to fix the a/c in the house. It started freezing up. Can't seem to get time to concentrate on just the car without other things popping up!

Thanks
