FYI-Went to pick up the head and the old guy at the Machine/Build shop asked if this thing had been sitting up for a while. I told him yes, about two years. He said I needed to drop the gas tank, dump it, clean it, dump it, clean it, spray it, flush the lines and change the filters. He cleaned and reseaded the valves. Everything checked out fine. Would do more work on it if I wanted to spend more money but didn't need to. Paid him $40 and brought it home.
This whole thread could have been avoided if I had cleaned the tank the day I drug it home.
I was going over everything with my dad a few weeks ago. He asked if I dropped the tank and cleaned it. I said no, just added cleaner and fresh gas. "Oh", he said, "I would have never have done anything without getting all that bad gas out first"
There is no telling what I am going to screw up one day when Dad's not around for advice.
