Dwell and Timing C"8"

Unknown

The book for the dwell on my 1952 C "8" calls for 27 degrees at a point setting of .017. With the points set at that amount, my dwell reads 22 to 23 degrees on my meter. Is this acceptable or should I try increasing the point gap. Other adjustments to attempt?

Also is it possible to obtain a reprint of the article about setting the timing using a vacuum gauge. I tried that but I did not have much movement in vacuum as I rotated the distributor. I was wondering that I did not have it hooked up right. The manual calls for static timing, which I did and fine tuned the timing with an AC timing light. This is ok for now since the front clip is off, but later jumping in and under the front inner fender well will be annoying.

We put an article about timing with a vacuum gage in our New England Chapter newsletter back in the Nov-Dec issue.



Drop me an email at XXXneceditor05@yahoo.com (drop the XXX) and I'll email you a copy.

Alex sent me a copy of the article which explained how to use a vacuum gauge to time an engine. After reading it I saw the mistake I had made.

Thanks again Alex.

Now if some one would answer the dwell question I will retune my Commodore.

Insufficient dwell is caused by a wide point gap. Are you setting the point gap on new points or used points? If the points are used, the rough surface can cause an erroneous point gap when using a feeler gauge. If the points are new, are you sure you not setting point gap wider then you want by having the feeler gauge twisted? You might try checking the point gap on all cylinders to verity that the distributor cam is not worn.
