Set the timing @ 5* with connectors shorted, no difference between that and 12*...
I also made a compression test;
135-140 psi on all cylinders except 4th where I got 120 psi. It?s a bit harder to get a good reading on 4th due to lack of space but I re-did it a couple of times w/ same result. I put some oil on the piston but no increase...
Valves timed according to specifications last summer.
