I'm having trouble with my 23 vanguard, no one can seem to figure out whats going on with it. Cranks up and idles fine, but once you engage that clutch and put it under any load it dies. Checked/cleaned carb,fuel,lines,gaskets. Getting 1.5in of vaccum at idle. This is my first time dealing with this kind of issue so i thought I would ask here for some insight! Thanks!
