I got an 89 trailboss that I’m try tl restore. Everytime i think i’m done something new pops up.as i. Guess it does everyone.so when i turn the gas on to the carb it starts coming out the small line at the bottom that two lines come together and enters a check valve that has a short piece on hose on it while i’m asking where does the small vac line that comes out of carb below where the choke cable enters the carb.thanks for anyy help
