What makes you suspect the carb jetting? The bog on acceleration could be the accellerator pump adjustment, or a leaking pump diaphragm. Unless the carb is defective, you should be fine with it, now and in the future. They aren't hard to disassemble (see if you can find a good book or do lots of Googling) and you can see what jets are currently in there - start off by knowing what you have. Does it have a choke (Manual or electric)? I don't know what your parts availability is over there, but you can get sets of gaskets and such so you can tinker all you want.

Once you know what your carb has in it, and that there's no crap i the bowl, and that the initial float levels are set and the accelerator pump is close to what it should be, then you can put it back on and get the timing set as mentioned above. Getting these 2 systems close to correct will give you a decent idea of what you should do next.

I have the Torker 340 on my 360. It has a lousy reputation, and I would/will change it when I can, but for now, the car runs fine with it. I'm not racing it, and it's summer here and I'm at sea level.

I know it's tempting to throw new parts on, but if doing that doesn't help or makes matters worse, then you just end up more frustrated.
