Hey guy,

I have a 1971 Ski Doo T'NT 399 and am curious about how the fuel lines work with the tilloston carb.

There are 2 fuel lines from the tank directly to the carb. One goes into the side and feeds it and the other is on the bottom of the filter. Is this correct? Is there a pulse line? I am having problems getting gas to the carb.

Thanks for your help!

Tiloston carb had the built in fuel pump. If you took it apart and cleaned it, there is a chance you got the diaphragm upside down.
