Went to start my W30 after sitting over the winter a couple of weeks ago and it wouldn't start.Son is home today so we towed it and it started up on only 2 cylinders. Turns out 2 cylinders had a stuck valve. I gave each valve a couple of taps and they popped up and seemed OK when I pressed on them a couple of times. I was wondering if I should spray something on the stems while I have it a part or just put it together and run it for a while.What would I spray them - just oil or something else.I only run this thing a couple of times a year as I don't think I have the pistons shimmed correctly on the crank shaft and it has no brakes.Maybe get around to fixing both this year.When it runs it runs as well as any tractor going.
