I just need to know what to set the timing at on a 1500 cc engine. I have no spec sticker to refer to. Thanks

This is taking me back some...have not seen one of these for years......

Spec's are usually a sticker on the underside of the hood with timing and valve gap clearances.

On the crank pulley is a notch or pointer for TDC . On the front cover, next to the pulley, are about 4 timing lines . The hood sticker tells you the notch to line position for timing as these lines on the cover where painted different colours.

Being as you have no sticker...time it at warm idle speed with the pulley pointer/notch to the first line on the cover with a timing light.

To highlight the marks you can dab them with White Out or similar. Without a timing light you can only approximate the timing be rolling the engine forward while watching for a spark from the #1spark lead jumping to ground with an old plug in the end of the wire.

Another way is to drive and then stop to advance the timing at the distributor until you hear pinging on full acceleration from low rpm's. Then back off the timing a few degrees until the pinging stops.

A l-o-n-g time ago....we used to time engines with a vacuum gauge plumbed into the manifold down stream of the throttle.

Run the warmed up engine at 3500 rpm steady, with vacuum lines to the distributor removed and plugged, advance the timing until highest vacuum reading...usually around 19 to 23 inches vac'. Then back the timing off 3 degrees or 2" to 3" inches of vacuum and leave it there.

Road test for performance and pinging.
