Wondering if this was true or not. Some guys at work were talking about something you can buy some type of liquid to put in motor to unstick your sticky vavles. I have never heard of it and was wondering. Thanks Mike

I had a neighbor with a Ford 9N that had chronic sticky valves. He put a pint of automatic transmission fluid in a full tank of gas and swore the problem cleared up. I know it's anecdotal evidence but he swears it works.

I've had good luck with SeaFoam.

I've had EXCELLENT luck with Seafoam.
My Honda CB900f had a stuck needle in at least one of the carbs so it would pee gas out when I shut it off. I put Seafoam in and within a couple weeks it totally stopped and it runs great. Amazing stuff.

Old time remedy around here was to pour baake fluid down the carburetor until she smoked up the shop real good and then do it again.Cheap and worked like a charm.

Like Mark/txgrn, I've had good luck with Marvel Mystery Oil. I add it to the gas for my tractor and all my small engines. If I have an engine with a stuck valve, I'll dump it in the spark plug hole, down the carb or whatever it takes to lube the valves.

Before I put my generator away, I always dump a little extra MMO in the gas, then run the gas dry. Since I started doing this, valve sticking on my 1950 vintage Briggs & Stratton has completely disappeared.

You can buy Marvel Mystery Oil in the red container at wally world. Goes in gas and oil. Then get the engine to injest some. Easy in a car just remove the air cleaner and pour it in the air intake till the engine almost chokes (lotta white smoke out the tailpipe) then let her catch her breath and do it again half a dozen times.

Then turn her off and let her sit for a couple of hours and do it again.

If the plugs don't clean up on their own, take em out, clean em up and stick em back in. Be surprised how good it works.

On an updraft carb on a tractor you will need a squirt device to get it in the airstream. Some folks use diesel.

I wouldn't put that in the intake of a late model car, you'll be buying O2 sensors in a little while.

Well we didn't. It was back in the early '60's. With the new clean fuels haven't had similar problems.
