First old tractor

Just an introduction, Donny from Delaware.
My grandfather has been asking me for years to come pick up his "old jubilee" and while borrowing a friends trailer that had an electric winch I figured might as well stop by and get it. After pulling all the blankets and boxes off it, I realize this is a nice tractor. Got it home and pressure washed and could not believe the condition.
once in the pole barn I soaked the cylinders and flushed out the old gas and ran great (until some old gas goo got to the intake valves). Now just waiting on new pushrods to put it back together

Nice tractor. It's a good thing you got it. Next thing you would have heard from your grandfather. I sold the tractor I didn't think you wanted it.
Nothing worse than old gas in an motor. It will really stick valves. I learned the hard way. Stan
 

Yea, I do a lot of "tinkering" with toys and this is the first time that I have seen gas turn to a black tar. I know the newer ethanal gas gets jelly after a few months in a carb, but this tar is tough.
 
If the Ethanol jellies after setting why hasnt that happened to me as we have been using the gas for well over 40yrs and
just do not have such a problem they set all winter unheated dirt floor building and start every spring with no problems your
people there must do something awful wrong
 
Gene I have decided it may be a location thing. This farm has over 30 gas engine devices. Things like concrete mixer or lawn aerator that may not see use twice a year. Countless weed eaters, chain saws, and on and on. I hear the I,ll Never use ethanol gas on here all the time We just do not experience that kind of problem. Sometimes if I pick up a chain saw that I know has not been used in awhile I,ll dump the gas but many times not. I think it may have to do with the weather where one is located because the normal is 10% e in regular gas. I don't doubt the ones having the problems but sure no problem here . (Middle Tennessee)
 
It's been sitting since 08-09, just pulled the head and cleaned and lapped the valves and the black tar was all on the intake side.
 
(quoted from post at 18:21:34 10/19/21) How did old gas getting to the valves
create a need for new push rods? Or am I
misreading it?

The varnish in that old gas can get the valves stuck so tight that it will bend the push rods trying to move them.
 
I don't understand gas and bent valves or push rods either. Never even heard of it. Out of time or other things do that not gas. News to me.

It has been awhile since I have seen reference to the bent push rods, but I remember it happening to SouNdguy for those who may remember him.
 

When I got my '59 F-350 it had not run in nearly 10 years. There was still gas in the tank. I added some more, replaced points, plugs, etc. and got it running. It ran beautifully--purred like a kitten! The next time I started it a week or so later, it barely ran--was missing so bad it sounded like a John Deere, and would barely pull itself. I limped it up to my mechanic and they found that several of the valves were stuck. Took some effort to get them freed up. I ended up getting a different gas tank because of all the crap this one had in it.
Didn't bend any push rods on that one, but I've read of several instances on other forums where it did happen.
