If you are sure your timing marks are right ten over advancing the base timing is just putting a bandaid on the problem. Sounds like a vacuum leak.



I'm pretty sure the timing marks are correct. We checked TDC when we degreed the cam. The cam was 2 degrees off so we installed a 2 degree offset key but now I'm wondering if we installed it backwards.

The vaccuum is steady at 19" at 30 degrees initial and 15" at 17 degrees initial, but it idles a bit rough at the lower setting and dies when put into gear.

I'll check for a leak just in case. Thanks for the suggestion.
