is the valve assy, air cut ( black plastic ) that goes on the carb. are you suppose to be able to blow air threw it? I know the two holes that go into the carb you can blow threw but the one tube on top that the rubber hose fits on and goes to the outside of the carb. are you suppose to be able to blow threw it? just tryin to figure out if it is clogged.....

thanks for any help

the little tube at the top is the one I cant blow threw or suck threw. just wanting to know if it is suppose to be like that or if air is suppose to go threw it.

This is how the repair manual says to check the valve. It sounds like yours is right, but to test it properly, you'll need to pull vacuum on the port where the hose goes and make sure the other two ports are cut off then.

k so i went out and duct tape my shop vac to the hose and tried spraying carb cleaner in the valve ports when the vac was one and the same thing happen fluid came out of the other side of the port ( not the vac port) know mattter which side i sprayed threw. but never flowed threw the vacuum port.

are you saying that when i have the vac on i should not be able to blow threw either valve ports?
with or without vac i can blow in one valve port and air will come out the othere valve port

with the vac on or off If I blow threw both valve ports at the same time nothing happens, my cheeks get real big.lol

I might be making this more confusing then what it is.

one of the valve ports looks like there is a lil black ball in the hole or am i just seeing things?

The manual seems to suggest that air shouldn't flow through the two valve ports when vacuum is applied to the vacuum port.

The little black ball that you're seeing is probably some type of check valve.
