figured it out, it was for the distributor vac line. for some reason the fitting was gone and the line was right next to where the hard line screws onto the auto choke. so it was connected to nothing lol. it runs now, the idle is super high though. which screws should be adjusted? the one on the right by the throttle linkage, the one on the left for the choke, or the two under the float on the front of the carb? I noticed one of those under the float was turned in twice as much as the other...
