Filled the tank with Metal Rescue let it sit for 6 or so hours then flushed out with a hose for about an hour. Looks pretty good, now to get it good and dry inside. When I put gas in it I'll put in some gas dry as extra measure. Its running on all four cylinders and sounds real good. the #3 carb had the needle valve stuck shut and was not letting any fuel in, a couple taps with the handle of a screwdriver and it stared to flow. I have a coolent tube leaking at the oring on the left side, easy fix there. Let her run for awhile to check the fan, It came on and ran till it cooled it down so all good there. Just have to change the timing belts when they arrive, clean it all up and deliver her to the owner.
