I started up a '74 ford 1 ton a month or so ago that had sit for several years. We drained the fuel tank and added fresh gas, primed the carb and started it up. It started (under protest) and would run but only over 1000RPM. It would not idle at all. I had my son hold it at around 2000-2500RPM while I poured MMO down it's throat. I would pour until it was about to stall then let it catch it's breath and do it again. Used 250ml all together. When the smoke cleared (and there was a LOT of smoke) it ran perfect and idled smoothly.
