I have a Mont Ward lawn tractor and need help identifying a part please.
Attached are two images of the part in question removed from the engine.
When this is attached to the engine and the small black hose coming off of it is attached to the air box, the engine will barely start and run very rough. When I remove the black hose from the air box, everything runs fine and strong.
I tried cleaning this part with carb cleaner and compressed air and it all looks good but still causes the engine to fail when it's reinstalled.
My guess is there is crud inside of it that I cannot clean out and it needs to be replaced.
But I can't order a new one because I don't know what it's called.
Please help if you can.
