Hey, guys! Thanks for all of the suggestions. It's been pretty cold here so I haven't been able to work on my bike for a while until today! (From 30 degrees last week to 60 Degrees today. lol
Good ole Texas weather.)
I finally pried the petcock off and hoo boy. Haha I'll attach some pictures.
Compared to some of the pictures I've seen of what they should look like, I don't think cleaning it would even be in the question.
Both the inlets are completely eaten away and both the tubes they lead to are full of hardened gunk. The second pictures is from the bottom of the petcock looking down the tubes that should let the gas flow to the carbs.
Am I right in thinking I should just buy a new one? My finger is hovering over the "order" button for a cheap one (8 bucks) on ebay.
