Here's the problem: Last spring we fired up my father in law's Super H and found it only would run on 3 cylinders. It had been sitting idle (inside) for 2+ years. When I removed the rocker box I found the #2 intake valve stuck down and the pushrod disengaged from the rocker arm. A generous application of WD-40 and some gentle tapping with a brass drift on the valve stem loosened it up. Reinstalled the pushrod, fired the motor and found the valve worked fine. Then checked the valve clearances (all were OK)and buttoned it back up. The tractor was then used for a total of maybe 2 hours, then parked back inside. This weekend we fired it up again after sitting idle for 12+ months. This time we found both the #2 and #3 intake valves stuck down and their pushrods disengaged. The WD-40 and brass drift treatment again loosened them up. Checked the pushrods for straightness (they were perfect) and set them back in. Valve clearance checked out and the tractor now runs fine on all 4 again. A restart yesterday found the engine running perfectly - no evidence of valve sticking. My question: Anything we do to prevent the valves from sticking again? The oil has been changed. I found the motor to be squeeky clean inside - FIL used good detergent oil and religiously changed it and filter when it was a working tractor. My only suggestion is to fire it up every couple of months and let it run until it's fully warmed up. I welcome others' experience/ideas. Thanks! ...Bob M
