Ok, so I finally got back out the garage checked the firing order and everything was as it should be.

I ended up taking the front end apart and made sure the timing marks were lined, they were. But I pulled the timing chain off and re installed it just to make sure.

I got it all back together and fired it up and it runs a lot better now...but there is still a couple issues.

The first is the timing mark is jumping and it seems rythmic. The timing will be there then every second or two is dissappears and the comes back....

I took it for a spin around the block and if I accelerate normal everything seems fine, but if I put my foot into it backfires.

Is this my timing chain is toast? or a vacuum leak? I did throw my vacuum gauge on it and at idle in gear the vacuum gauge showed 15 and it pretty steady..... I threw in the towel late last night and am going to step away from it for a day or two, but any ideas would be great! thanks - Brian
