Tecumseh adjustable tappets?

[Old_Brewer]

Hi all
I have a Tecumseh tvs120 63911h 5 HP L-head engine on a Sears 917.372480 self-propelled mower. I can start it, but my wife has a hard time with the pull starter. I thought about adjusting the valves. Does anyone know if the valves are adjustable? I am unable to tell from the parts diagram. The mower runs fine, has good compression. It's just old.
Thanks

the only way to adjust the valves, is to remove them and grind the stems to increase clearance, which in your case will cause the opposite of what you are wanting to achieve.

Thanks. At least the mower is still usable. Pretty good for a 20 year old mower.

I have a 89 toro with a Tec engine. It starts on one pull. But when it does not it is the end that screws on the spark plug that the plug wire attaches to is loose or has some corrosion in the threads. I do not know why it becomes loose now and then but it does and then it is hard to start. Those engines do seem hard to pull over.
