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.

That is a crankcase breather or pcv valve. 

 I don't see how it could make that much difference when removed from the air box.  I wonder if your air filter is plugged?  If you can blow through there with your mouth it is OK.

Hi Scottw welcome to our forum. I am thinking that is some sort of crankcase breather but I am no expert. I am sure someone will be along soon to help that knows more than I do.. But I have to ask you are you sure your engine oil does not have fuel in it?

Welcome to GTT. You can download the Briggs and Stratton Manual to learn more about the breather. I would suspect that your airfilter is plugged. Good Luck, Rick

Like was said, can you blow freely through that rubber tube?   In either case, keep us informed. We're always interested in what our members are doing. :welcome:

That is indeed the crankcase breather. 

 

I don't really understand, though, how the engine can run that much better when you disconnect the rubber tube from the air filter.  Maybe, I'm wrong, but that just can't be unless (like it has been suggested) the air filter is clogged.  You would have more problems than just a breather if the air filter is that clogged. 

 

When you hook up the hose, does it put pressure on a hose or a linkage or some sort?   Does it twist a spark plug wire?
