ran out of propane

[outdoorsmadness]

love this site, i learned alot but aint there yet. i built a cm still and after running a vineager run and an alcohol cleaning run i decided to convert it into a vm. i have a 2 inch collum 40 inches high 12 inch collum above that with a double wrap coil with a cold finger. take off arm is 1 and half with a 1 inch gate valve. liebig is 23 inches long. after building i ran another vinager run and used my cleaning feints after that. then for my first real run i used birdwatchers recipie, 6 gal.i let it equliberum for about an 1 and a half at full reflux then cracked gate vale open and took off at 1 drip per second untill i coolected 50 ml. then i re equliberum for 30 more min and took off heads at same rate untill temp reached 172 in takeoff arm. collected about 650 ml. when i started taking my hearts i open gate valve till i was gatting almost a small stream, the temp would flucuate between 172.9 to 171.3.( is this because i dont have my collum insulated?) then later flutuating between 176 to 174 and similar temps throughout run. when it got to be about 177.1 i ran out of propane. i collected a little more than a quart and a half of 92% but i know there was more to go. whole process took about 6 hrs would it be alright to let it sit for a couple of days then run again real fast to get the rest to add to my feints or should i toss. airing out my spirits now cant wait to cut and drink.
