I recently bought a 120Y that has a rebuilt 14a engine that has extractors, a mild cam and apparently a carby from an 1100 .
When I put my foot down to it was hesitating before accellerating or revving. I had a spare carby that I put on today which fixed that problem.
But still if I try to accelerate hard in second at low revs it kind of stumbles then picks up but if its higher revs its usually ok. And if I'm cornering hard and try to accellerate out of the corner it does the same thing, like there isn't enough fuel for the engine or something.
Do you thing the carbs too small? Any other suggestions?
Thanks
