ran great before i thoroughly cleaned the carb and replaced the choke cable on my 85 250x. if i pin it, it bogs out bad and is now difficult to start. i'm thinking it's getting too much fuel. if pulling the carb off of this wasn't such a pain in the butt i'd just do it and make adjustments but it's a nightmare. I do notice that the vent tubes have fallen off. I dont think they are that important but there are like 3 that all connect together. Any ideas?
