2004 Polaris trailblazer 250 Vacuum lines

[Tom T.]

I have an '04 trailblazer 250 and have a problem with the vac. lines on it. One goes from side of carb to the bowl, Where does the other end go/ next there is a port next to where the choke cable screws into the carb. the line was melted when I got it and have no idea where it goes. Can anyone help me out with this?  Thanks guys

there should be one going to the petcock

Petcock ? The fuel shut off valve?

[drag_on]

yep

Guess I'm screwed cause there is no place on the petcock to hook it up. Besides I have to tear it back down because I have only 30 psi compression. But thanks for your help

There's no vacuum  line  to the petcock.. The  line from it to the carb  is the fuel  line.

30  psi  compression is likely  one of 3 things .....  Either  the valves are not set right  and being  held open slightly, the  rings  are  shot / cylinder may also be  scored or possibly  the  cam timing  is way  out  so  the  valves are opening and closing at the wrong points  in the cycle.
