All the spark plugs looked identical and good. I was surprised when I compared them. Compression ratio was all over the place, 140-185. 185 was on the missing cylinder. Exhaust

All the spark plugs looked identical and good. I was surprised when I compared them. Compression ratio was all over the place, 140-185. 185 was on the missing cylinder. Exhaust gap was up to .002 under spec on the low ones. Picked up the shims last night and they're in. Waiting on the injector rebuild kit to go to the next step. Hopefully they show up tonight. This is an old single coil motor so coil should be good.
