Did the seafoam trick, ran 30 minutes, and its now about 140 psi
Now all cylinders are 140 to 155, should be good, right?
Only thing that concerns me is the smoke in the exhaust but I think thats from the gas being old and the seafoam in there. It wasn't smoking much at startup tonight but after the seafoam got to the carb it started. Hopefully it all goes mostly away with new gas.
