one more little problem

[Annox83]

thanks to all for the info after on the last thread " it makes a buzzing noise...". I got it working today after...They replaced the battery and it's fine now. but there's another problem. when I took it for a spin today not for long.. when I clutched to move up gear the it started to rev higher... the only way I can turn it on is by having the choke on.. also it revs like mad when it has started.. any ideas?

your carb idle screw must be turned up .

sounds like an air leak on the inlet manifold
