Gas leak


I got my LX178 out of the shed from having sat all winter and found that I have gas leaking from what looks like a metal sediment bulb which is dripping on to my muffler. Any suggestions as to why I would have this dripping? Any thing I can do to stop it without taking it to the dealer?

Re: Gas leak


What you are describing sounds like the carburetor bowl. The bowl is mounted by a bolt up through the bottom which also has a fibre washer. If it was left full of gas it may have deteriorated the washer. You can try to source that washer through a JD dealer but it may come as part or a kit.

Check to confirm that where it is leaking from and you are not just seeing fuel leaking down from someplace else.

Re: Gas leak

Re: Gas leak


My now 24 year old John Deere started leaking gas in 2016, but it is not a lawn tractor...its a old tiller. I removed the leaking bowl, cleaned it out and flipped the washer over.

My JD carb bowl is still dry today, no leaks from it. Just got lucky I guess. Love my old Deere. I have not spent one dime on it in 24 years except annual oil changes/spark plug in its old Tecumseh engine and have worked it like a pair of mules. Not even a drive belt changed.
