As for the petcock, the kit tank and kit supplied petcocks are a 10mm machine thread, not a tapered pipe thread. There should have been a red gasket, about dime sized that was meant to seal the kit petcock to the tank. It appears that you have replaced the kit valve with another type which I will guess is 1/8" male pipe thread.
If that's the case it will probably turn in a little, it should be tighter than finger tight anyway, to rotate the fuel line to where you need it. In your case I would have used a straight petcock instead of the 90 degree one you have which would have aimed the fuel line more directly toward the carb.
Good luck.

Again, thanks for the advice. I will put the stock petcock back on to have it aiming down and that will do for my 1st build. (I do have the red gasket on there) I can always use the other one for something fancy smancy later.
