DRZ400 questions

Hi all,

Can someone tell me what this outlet on the base of the carb is for? I assumed it was just an overflow for the bowl but when i turn the fuel tap on after 10 seconds it starts pouring out fuel. Should it be connected to something else? Also theres a tube thats just been capped off with a screw, any ideas if its for something essential? And lastly theres a crack in the side cover from the gear selector crushing into it in a crash im guessing. Does anyone know if the cover is just alloy, so i can weld it up? or is it something weird like magnesium etc?

Ive attached some pics below for reference. Cheers.

It looks like the coast enricher has been removed, the hose that has the bolt in it off the intake used to run to it, there are 2 other nipples on the carb that went to it. Probably good to finish the job properly, either plug all 3 and increase the air jet to a 100 or plug the one on the head side and run a hose between the other 2.
The other one with the arrow looks like the overflow from that angle,could be a stuck needle or float level wrong. Try tapping the bowl while the tap is on and see if it frees the needle.
Not sure if the cover is aluminium,liquid steel may work.
