Make sure your flue is clear and that the burner(s) light without delay.
You might be getting a puff while they light that puts a smaller pilot
flame out.

Oh yeah, the main burners light as soon as the solenoid sounds, that
was always the case. Seems like the pilot would go out after the main
burners turned off and not when it kicked in as I had originally
thought. Anyway, it's working fine now after further adjustment. I
adjusted the pilot gas flow so that it took the specified one minute
to stay on when lit from cold. Thermocouple glows red now, however,
the flame is about half as intense as before. Going to replace the
pilot burner assembly as well, orifice may be degraded, it's 28 years
old.
