Water heater pilot won't light

Medic502

Not sure if I posted in correct category... 
 I have tried everything I know...the heater was not lit for approximately 1 month and now pilot will not light. Never had any issues lighting before. 
Cleaned the pilot tube and orifice...
Verified gas is coming out of bottom of gas valve when pressing down on knob in pilot position.
Spark igniter is sparking.
The only other thing that I am not sure of is the connection for the thermocouple to the gas  valve... On the end of thermocouple the threads are not very good and won't tighten very tight to the gas valve... Could this be an issue? 
Thanks for any advice.

Why does it look wet? Are you sure it is gas and not air, are you sure that while it was off it didn't get some air in it that you are now trying to purge out through the pilot? Will it light with a bbq lighter or something like that? It should light without the thremocouple, it will just go out as soon as you let go of the button. Make sure the pilot burner doesn't have a spider's nest or lint or water or something in it.

I was having trouble getting the screw out that held the pilot assembly to the burner and used some WD40... So that is why that looks wet. 

I had the gas company come by and they told me that there was gas coming out of bottom of gas valve and they thought the pilot tube needed cleaning was blocked...and I haven't tried to light with a regular lighter. But I guess I could try that.

I just don't know a lot about working with gas.
I can blow through the tube...Pilot orifice has been cleaned and I can see the opening.

I think the pilot should light even if the thermocouple is bad.

The thermocouple does need replacement however it's all twisted up.
