I changed the carbs and it seems to run fine but as soon as I get on the gas it dies out. Has anyone run into this problem before? What do you think it could be? Throttle linkages? Maybe its not jetted correctly? It revs up fine with the choke on, as soon as I take the choke off it idles, but once I give it gas it dies out. Also, the top center of the carb has a fitting with a vacuum hose that goes to it. I believe it is just a hose just for overflow but can anyone confirm? Does anyone have any pics of the routing of the vacuum hoses? I think mine might be routed differently.. Below, I labelled where the hoses go on the carb I have.
