i got a standard carb 20.5 dellorto an nrg 50 tank an how can i check if the petrol cap thing is ok cause when i take the petrol tube of the carb petrol poors out so im guessing its ok
it shodent piss out ,it shouldcome out wen u suck on the vacuim tube, try changing the petrol tank worth a try
most taps are the same any piaagio 1 shold do and imnot sayin %100 that it is that . and check your choke wires are pluged in probrly
long filter tap fits.. the runners are shorter and smaller diameter take the choke out the carb, turn the bike on then off.. the choke should move
i had same kind of problem as you this turned out to be the fuel tap i opted to use a gravity fed tap i used a oil tank tap and it works perfectly
so ye, your 3 pages of "help me help me help me" in the most impatient manner resulted in everyone telling you what i told you in the first place... get a haynes manual befor you start mesing wiht things you dont know about. oh and fix all the shitty bodges on your bike (im sure its coverd in them, its an nrg 125 wc ffs)
