Snake OIl?

[Geo-TH,In]

I had the #4 exhaust valve stuck open on my
Jubilee.
I thought everyone read yesterday's post.

You missed it, my Jubilee is in a retirement home after I bought a Kubota 4 years ago. She is unemployed.

What do people do if they have a parade tractor that sees little work?

you could try a premium synthetic oil and get one with high zinc like AMSOIL Z-rod. may help clean out what might make it stick. (??) for fuel try their quickshot. cures gummy carbs and also dissipates alcohol.

of course getting rec-90 non ethanol gas is best idea. we finally have a station in town now that carries it.

Frankly? Nothing. Having exhaust valves stick or any valves for that matter is not common especially if the tractor is started periodically. There had to be a preexisting condition that caused the valve to hang up.

Right now I have 10 tractors that barely get started a couple of times a year. Not a single stuck valve among them.

back before multi weight oils, the basic oil was full of paraffin and wax on the heavy side and lighter distillates on the upper side. SO... the paraffin would sludge out, and the lighter product would boil off making the oil that was left get thicker. So much for 30wt oils.

SO.. anything that would thin down or cut wax was a miracle product and worked well.

Today a modern hd 15w-40 has non of those problems if run often enough. Still sitting long periods, with high moisture will try to rust up most anything. If your not running a modern high detergent hd oil, then yes you need lots of snake oil and some magic.

I think that starting it up occasionally and NOT letting it get to FULL TEMP!!!!!!! only serves to create lot of condensation and makes the problem worse than not starting it at all. When you start it, set it up to 1200 rpms minimun and run it till the temp comes up fulling and the water is hot and circulating. Seals stay soft, bearing/mains are well lubricated, and any moisture is pushed out the vent. Any cold starting carbon is expelled, and detergent oil has time to clean and coat everthing.

One could put a block heater on a thermostat to keep it from getting super cold and condensating, as that might help??

MMO in both the gas and oil,splash some on the rockers while you have the cover off.

This is my second sticky valve.
One was on my 20 hp kohler command 2 years ago.
This is my second sticky valve on the Jubilee.

Both Tractors don't see a lot of work anymore.

Count your blessings.

See the water inside the valve cover and on the
concrete.
There is a vent next to where the water is.
Vent allows moisture to get trapped under the
valve cover. There is also a vent at the filler
cap.
I'm closing off the valve cover vent and
installing a PVC valve.

What's the worst can happen? More sticky valves?

Reduced the cost of driving ?...If you believe that line of propaganda I have some
discount ocean front property in Arizona that I want you to invest in.

The thing about snake oil is nobody ever does a controlled test. If you had two identical Jubes in your barn, you could run MMO in one and straight gas in the other and see which one gets a stuck valve. Ideally you'd repeat the test for a dozen or so times until you were sure your results were consistent. But you don't have two tractors and twenty years to run your tests, so it becomes a matter of faith.

Speaking of faith, George, some folks here believe you can fix a stuck valve with prayer. You didn't happen to throw in a few Hail Marys just to be safe, did you?

Seafoam for all my gas powered equipment, I did use MMO in my 1966 MF 135, along with seafoam to free a valve. Didn't take long to free it, maybe 1/2 hour of run time.

marvel mystery oil works.will clean sludge n junk out.run it get engine hot a few times change oil add some more mmo with new oil n it be ok
its been around still in use longer than prolly 80% of us here on yt. if it wasnt good it woulda dried up n be history
i mix kerosene n mmo half n half for penetrating oil n beats that pb blaster
