Timing

Trailbeast,

I just heated the engine up and pulled all the plugs as soon a it cooled down a bit. Did a compression test.

Here are the numbers. With notes. Also all were cranked for 8 seconds.

1 150 Reached that number in about 3 seconds
2 155 Ditto
3 150 Ditto
4 160 Ditto
5 150 Ditto
6 140 Took about 5 seconds to reach this mark.
7 130 Took almost the full 8 seconds to get here.
8 165 Took about 3 seconds.

So another leak down, but I suspect that # 7 has a valve problem. I am going to try a different approach and just pump a ton of air into the cylinder and see of I can spot listen for a different sound in intake as well as exhaust from a known good cylinder like # 4. Will also do #6 as it is showing a tad low and it reacted much like #7.

I am going to assume that when a cylinder takes longer to reach max compression that this is likely valve. Would seem odd to be rings I would think.
