I am at my inlaws cabin and had a problem with the pilot not lighting or staying lit. I replaced the thermocouple with this. Pilot lights easily now but I suspect the pilot is too much. What I think is the adjustment screw is totally tight (screw with the driver in it in photo). Is there somewhere else to adjust or is it ok amount?

Thanks for the help!

Update:
after more research I figured out the screw I was tighening was just a "cover" screw. Removed it and was ableto adjust the pilot down.

Does this look ok?

The pilot flame should be strong and fully engulf the thermopile and the thermocouple. It also needs to be strong enough to extend far enough over the burner pan to properly ignite the main burner.
Lowering the pilot flame can cause voltage drop on the thermopile which will cause erratic main burner operation.

It will cause voltage drop on the thermocouple causing pilot outage.

It will cause delayed ignition on the main burner.

In 33 years i have never had to adjust a pilot down.
