Help needed with F409 150cc

[Girvo]

Hi all,

I just replaced the throttle cable on my scooter after it snapped.

I installed it all fine, but now it's running at about 50% of its previous ability. I'm maxing out at 60kmh, whereas before I could do 110 easily, and I'm really struggling to climb hills.
The only thing I've touched has been the throttle cable.

Can anyone think what I've done wrong here? I'm at my wits end

you may have to adjust the "idle screw" or the "tube & nut(s)"
and of course you used a genuine TGB part?

Outstanding works great.
