On the carb for my trailboss it has two tubes that connect to one with a vacuum thing. Well what do I need to know about the tubes and about the and which way to put the vacuum. Any Help would be great thanks........

 

You'll need to check in your repair manual, or on another machine, but if I remember right, I just sold my 90 trailboss 250, and there were no vacuum tubes on it, there was a fuel inlet and two fuel overflow tubes that I do believe joined together under the carb and then dropped down through the frame through a check valve so that no water or such could get pushed up into the carb. Like I say though, it has been over a year since I had it apart so I'm not sure, but I don't remember two strokes having any vacuum tubes.
