  • Use a nitrile O ring.Best to take the muffler out, makes it easier to thread the gas line into the valve.DO NOT remove the bottom gas line fitting from the gas filter.Take out the bolt that holds the filter to the carb.Do not put Marvel Mystery Oil in your gas.It will attack original O rings.They harden up and make it hard to turn the valve.Then the O ring breaks up and you have a king sized leak.Never use plumbers tape on gas lines because little bits of the tape can get into the carb and plug jets.Do not remove the shut off valve from the tank.You could strip or break the mounting screws.Ive never seen a leak between the valve and tank.Be careful that the bolts holding the tank are not to long because that can start a leak at the front of the tank.Now write all this down in a note book.I am 79 years old and may not be able to post this info again.Paint the bottom of the tank white while its out, makes it easy to find leaks.

  • The best thing to do is if it's leaking around the cut off screw is replace the valve and not use it to cut of the gas at all. Put an inline cut off somewhere else. I've put cutoffs in other places with success . Depending on what style intake you have, you can put it right above your fuel bowl. On a 601, I routed a new fuel line to the right hand side of tank bottom with very easy access to cut off. I was kinda worried that gas wouldn't flow if the tractor was on a steep bank with the cut off up the hill, but amazingly, it ran for 20 min , setting there at 3/4 throttle 😄

  • I may have missed something here, but where is the leak? If it is on a threaded fitting I always wrap it with plumbers tape, if a tapered ( compression fitting) I've even slid the nut down and put a layer of plumbers tape around the flare,one layer will do it.I have other ideas but need to know where the leak is, God Bless, Beth and Allen.

  • The shut off on my 601 leaked, replaced by the previous owner. I bought a new one from just 8-ns. So far, so good. Now I have a run issue with the carb I rebuilt.

  • The O RING gets a lot of wear if you open it all the way.I can plow or bale hay on 2 turns open.Opening it all the way wears out the O ring.
