Dwell setting

Months ago I initially set my dwell at 32, initial timing at 4b and now went to check all settings and dwell is around 18-20. If I try to set it to 32 it stalls out at around 25.

What's up here?

Thanks for any help!

Re: Dwell setting

how are you reading the dwell with a feeler or digital meter?

Re: Dwell setting

Easy to remember;

If the dwell number is too small, the points are too wide.

I know that isn't what you asked, but it may help in your diagnosis.

Re: Dwell setting

Bump up your initial and try setting the dwell to 30.

Re: Dwell setting

This may not be helpful--my attempts at helping often end in my being asked to stop...
But, dwell and point gap are the same things measured differently. Just look at what the dwell adjustment adjusts. Point gap.
Changing dwell/gap impacts timing slightly, but not the other way around.

Re: Dwell setting

New points - 30* dwell, used - 28*.
Set your initial timing between 14-16* BTDC. When the factory set the timing it was to pass emission tests back in the day and so you wouldn't blow the engine up under warranty. If you want the car to run like a turtle then use the factory timing specs.

My first guess is that your meter is or was incorrect.

As the point block wears, the dwell # goes up (more narrow point gap).

Pull the cap and set them with a feeler gauge.

Re: Dwell setting

One degree of dwell change results in two degrees of timing change. Since you're increasing dwell, timing will retard. Not a surprise it stalled out. When it's off by more than a couple of degrees you have to jump back and forth between timing and dwell.

Re: Dwell setting

Set the points first then the timing.
