Pet cock leaks when opening it
 

On my 129, I generally keep the gas turned off since there seems to be an occasional leak somewhere at the carb. Today, when I opened the petcock prior to using the tractor, I noticed the shaft seems sort of loose and gas runs down from the top of the petcock. I tried tightening the nut directly above the shaft, but that didn't help. The obvious fix is to just replace the petcock, but thought I'd mention it anyway. Any suggestions other than replacement? Right now I have it open all the way and there is no leak from it - only when turning it. And, at this point, from messing with it, it leaks when all the way closed as well.

Petcock (referred to as "shut-off valve" on the parts website) appears to be part #951-3015 (replaces 751-3015). Looks like it's all one assembly. Price is listed as $21.52. I'll probably shop around and compare.

The packing material is wore out. I used a couple of small o-rings when I had that same problem.

Thanks. I'll just buy one. Hate, though, when a $16 item also has $10 shipping. Found one on eBay for $45🤪 I'll pass on that.

Search eBay for sediment bowl.

Thanks, but it appears those don't have a threaded piece that would screw into the bottom of the tank (?) :bigthink:

On ebay, using the advance search feature and the key words "cub cadet sediment bowl" gets you this

Try to tighten the nut on the petcock, you have to open the valve to get it to tighten.

I tried to tighten this nut but it was bottomed out. To compress the packing under it, I loosened the nut and wrapped it with teflon tape. Then I was able to tighten the nut and stop the leak.

I bought one at my local lawnmower/small engine repair shop for about $11. You could also go with a little red, in-line shut off if you wanted to. Those usually sell for around $3 or so, but then you have to buy the clamps to secure the hose line to both ends of the in-line shut off. If your carb leaks, it sounds like it is time for a rebuild. If funds are available, the rebuild kit is usually $8-$12 for those and it will also help improve the performance of your cub.
