If all else fails;
They stop oil from your valve stems from getting to your spark plugs. Oil continually runs off rocker arm tips to lube valves. Stem seals seal off the stems.Hi Roustabout,
What are umbrella cup valve stem seals and why would they help?
Thanks
Thank you, I get that now.They stop oil from your valve stems from getting to your spark plugs. Oil continually runs off rocker arm tips to lube valves. Stem seals seal off the stems.
Hi,A hotter plug will help this problem. Also make sure that your mixture setting is not too rich, your ignition timing is correct, and the point dwell is per spec. Does your engine hit the correct coolant temperature during your duty cycle? If it doesn't warm up, that could contribute to the problem.
Hi,You mentioned a new cap, rotor and plug wires but what about the condenser???
Champion N21 is the proper plug for your tractor. I was a massey mechanic for years.A hotter plug will help this problem.
