I've got an old Ford 351W which has caused me many problems. total hours are around 800. I have two current problems that may be connected. Last year the motor stopped running. We pulled a head saw water in the cylinders, replaced the head gasket and after some tweaking the boat ran great. Later in the summer I began fouling plugs. the motor has a relatively fresh Holly 650 boat specific carb and a mechanic thinks the rear barrels are dumping gas into the motor. It does often run rich at low speeds. I changed the plugs multiple times which only temporarily solved the problem before they fouled again.
Now for problem #2, When stored at the end of the season I learned there was water in the oil. Could the head gasket installation be faulty? could the block be cracked? instead of pumping in antifreeze we drained the block. Could the water detected be residual water from the earlier gasket problem? What should I do? Pull the carb,and make sure it's right with a clean needle and seat then just run it and change the oil a few times to see if the water works itself out. If it doesn't, I could pull the head(s) and replace the gaskets again and then hope it goes away. Otherwise it's probably the block.
Complicated, I know. Any insights are welcome. Thanks
