Okay. Thanks to all who helped me fix this issue. After trying many different ideas it WAS the head gasket. I replaced the head gasket and there were no more leaks. Since it's getting to be cooler here now I'm not sure how much I'll be using the mower so I'll have to keep an eye on it next...

Ok. So I have a little bit of diagnosing to do this weekend. I actually believe it’s the head gasket because from what I’ve been reading, these engines are notorious for blowing head gaskets. I will post my findings for sure. I appreciate all the help.

No to both. I had been running the mower since spring after it's initial tune up. I haven't had the problem until now and I haven't added any oil to the engine since this spring.

Interesting ideas that I will try. One question: When doing the pressure test with my hand, should I feel a vacuum trying to suck air or should it be no suction at all?

I don't believe so but I will check. Thanks.

I can't see any holes. I put it in a bucket of water and blew air into it and I got no bubbles. I'm pretty sure it's coming from the pump itself.

What if it’s not coming out of the brass filter but the little slots around the brass filter? Same thing? Blown gasket?

That was an OEM but I will buy another and see what happens. I will post back here with the results. Thanks for everyone's help.

Ok. I think I've isolated the area where the leak is coming from. It's either coming from the brass looking circle on the fuel pump or the little slot holes that go all around the pump. It's a brand new fuel pump but could it be bad too?

Thanks all. I will try everything mentioned and post back my results.

Ok. I will try that.

Thanks, but it's not coming from the carb. It's coming either out of the fuel pump or a crack in the line from the fuel pump to the carb.

The breather hose looks fine. I took it off and inspected it.

Could this be the model number? 331877-0117-G1 Thanks StarTech!

Sorry guys. Got bogged down with flooding. Anyway, the B&S model 929133 540cc 21.0 J1940 (?). I tried to send a couple of pictures but I don't know how to make them smaller so they could be sent.

Thank you and I will in the morning. I am working tonight.

I have a Hustler Sport 48" ZTR with a 21 HP Briggs and Stratton engine. I noticed after mowing I had a bad oil leak coming from the oil pump to the carburetor. I inspected the line and saw no tears or holes so I thought it was the oil pump. I bought an OEM oil pump and installed it. The next...

Awesome info on what to do. After I read it all I started from the first step and worked through it. As I was doing the steps I noticed that my battery was wedged up against one of the brackets holding it down and it was making contact with the post. I moved the battery slightly away from the...

My Hustler Sport wouldn't start because of a bad battery. I couldn't even jump it. It would try to crank but never got enough juice as it would do a slow turn followed by the clicking noise.. I replaced it with a new battery and now it hums real loud when I turn the key but still won't start...

Hi all. I just purchased a used 48" Hustler Sport ZTR and need to change the oil. It looks like I'm missing the oil drain hose (part 104786). Do I actually need that hose or can I just buy a rubber hose with the same inside diameter to use instead? If so, does anyone know what the inside...
