#1 they look like jagged casting flaws into the 2 carb bowl mount screw areas...problem?
#2 P/o broke off the jacket surrounding half the idle jet.....problem?

If not, you may want to post up a wanted ad and see if anyone who'se put an aftermarket float bowl on wants to get rid of their stocker...
Birdy - he can't do that - That's part of the carb, NOT the bowl.....
I'm with Birdy - try to jb weld the part on, if you don't have the part , hmm- ever completely create something new out of JB weld - I think it's possible - replicate the piece (outer dimension) by filling an appropriately drilled piece of plaster, remove plaster, drill appropriate inner hole - so now you'd have a JB weld tube, grind away JB weld until you're left with a piece the shape of the broken off corner, then JB weld the JB weld piece onto the carb......

Im more worried about the broken shroud around the idle jet. However, there is another plastic peice that goes around the whole thing.... the Previous owner broke the metal peice off so i dont have it. should I break the other side off so the flow is even?
The fuel still has to go through the jet as a metering orfice. so hopefully i will be fine

That portion of the casting may well act as a "straw" to draw fuel from the bowl, so if you cut a portion of the straw away on one side it'll start to suck air unless you raise the fuel level beyond that (a definite no no) - that's why fixing it might resolve any issues you might be having.
If you decide to fix it, make sure you take the jet out before fixing it so you can clean up any squished out JB weld with a drill after it's cured.
