peugeo speedakes a feckin head ache

Right so in my last post i complained my speedake/buxy's rear whell wasnt moving, found out that it was the clutch in my new carb, so got thatfixed but im still having problems, this time i think its jet sizes in the carb. I have a 70cc big bore kit and a leo vince zx exhaust. Could any one tell me just roughly wat size of jets i should b using, when i used the 1.05 it got worse. i currently have the bob standard carb and jets on it and it seems to go well lthough the accelration is slow but i do neede to upgrade my rollers for it, please help if you can via email, my email address is willie19a@hotmail.com, i would appretiate any help atall because im so close to getting it right but everything i do seems to take me futher away from getting it right lol, maybe i should have just taken it to the garage but the best way to learn is surely to do it by yourself imp:

 

oh and yeah i forgot to say, with the old carb on, would it make any difference if i changed the air filter or is that not really nessasery for the scooter to run right
