    The reason you're supposed to pull the plugs out is so there is no compression, and thus no significant force pushing down on the connecting rod journals as the enigne turns over. That way you don't wipe out the babbit layer on the dry bearings.

      there is no reason for old gas not to fire... my 1965 ford thunderbird sat on my farm for about 20 years... when we finally pulled it out of the blackberry bush my dad drained the gas out of the tank and poured it into our 89 mazda B2200... it ran fine just stunk really bad out of the tailpipe... but something we have discovered about old gas, if you are in a area where there is emissions control, old gas will get the smokiest old peice for shit to pass the test... dont know why but thats the only way to get my 83 chev celebrity 2.8L to pass... and that motor is in seriously rough shape...

      so, as far as my experiences have taught me, old gas will run fine...

      and as for starting it up every month, waist of time. my t-bird has been sitting for 20+ years and the stock 390 is a turn key startup and i only recently started firing it up i guess last year. no leaks, no problems AT ALL.

      oh and my 81 dodge power ram 440 sat for 2 years at my grandparents house with no carb on it. the intake manifold was really rusty, like really rusty. i put a carb on it and a charged battery and put the pulley sistem back on and litterally about 10 seconds of cranking (to get the fuel up to the carb and fill the bowls) she fired up and puffed a bunch of blue out and away i went.

      I am currently driving it everyday since the tranny in my cutty is blown.

      didnt do no draining of the tank or nothing. changed the oil after initial fire up and a new cap, rotor, plugs, leads, and a rebuild on the Holley 650 and she went just fine till i blew the transfer case last sunday 4xing. (just finished rebuilding that today and is going back in tomorow)

      so take whatever advice you want out of my little speach... just pesonal experiences... but you are best of to learn our own lessons... otherwise what is life for if you just do what people tell you to and never learn anything for yourself?
