I just got this carb can someone please tell me where the vacuum hose barb coming off the rear pull off goes? It has only the rear pull off. It's got one vacuum line to the carb then a big one right off the back of the pull off that I'm not sure about. The numbers for this carb is 17084226. Any help is greatly appreciated.
Never mind. I think I see what you are referring to.
Is this the rear pull-off in question?
I believe that is an adjustment for something on the secondary side. Maybe the secondary air valves.
Cliff will know 100% what it's function is, but I don't believe that is a "vacuum" port.
