i bolted up the pz19 i got off ebay to my bike,and it runs real shitty with this carb on,when i bolted the PZ19 back up,it revved more freely and much higher,i was told this is because it needs to be jetted,so can anyone help me out here and explain to me how i go about rejetting.
i know how to take the jets out,i just dont know the differences between jets(like a #72 or a #52 if you get what i mean).

Have you messed with the fuel air screw. That is just to make it richer and leaner. You can also check your spark plug to see if it is too rich or too lean. When does the bike cut out and is it a 70cc or 90?

Baja Dirtrunner 90 (now 107cc) - xr70 aftermarket exhaust, uni air filter, head breather, xr50 aftermarket footpegs, straight up style kickstarter, suspension lift mod, 52.4mm piston and rings(to bring displacement to 107), black SDG skid plate, xr50 foot-brake modded, dice tire caps ;), and more to come

tried messing with the air screw,no go,the spark plug was pitch black,and what do you mean by cut out?
soundwise instead of revving real high,it would only rev halfway,its the 70cc version.
