I have a '74 ford 1 ton that my son wanted to use. It had been sitting for years. We pulled it out of the shed, drained the old gas and put fresh gas in it and a battery and started it up. Started but ran like crap. Would not run under 1000 RPM at all. Had my son hold it at about 2500 RPM while I poured MMO into the carb. Would pour until the engine would start to slow, then wait for it to "catch it's breath" then pour some more. Used about 250ml (8 oz) and when the smoke cleared (literally) it idled perfectly.
