My valves will not stay in adjustment Kohler CV13S

Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

2 weeks

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes

Mechanic's Assistant: Anything else we should know to help you best?

Why the cv13s engine will not run with valves completely tightened down. adjusted as if it had solid lifters and the engine run fine until the adjustment bolt comes loose it comes loose very shortley after qadjusting

Mechanic's Assistant: Can you guesstimate how old the engine is? And has it done anything like this in the past?

There is a screw only for the adjustment - no washer just the screw I have no idea the age
