Strange Slant 6

i was thinking a lean condition too. it only takes something the size of a single coffee ground to really mess things up. i would look at the carb. the oil missing is odd though. when was the last time it was checked before noticing it was that low? what does the coolant look like?

Coolant is still bright green, except for a little bit of rust in it. Oil was checked 15 miles before it started running terrible, and was full, then after 15 miles it would barely touch the end of the stick. If its the carb, I certainly do not want to put it on this new crate motor and mess it up too.
