Hi guys, my breather pipe on my quicksilver snapped off so replaced it with a new 1 but after replacing i took the car out for a small run to make sure all was well. But the engine seemed to be struggling and then as i slowed down to change down gear the engine stalled. After restarting i realised that when i was slowing down at another corner while i had my foot on the clutch the revs were not settling around 1k and a couple of times actually just 0, just had a new clutch fitted 2 weeks ago so cant see it being that. To start it now i need to give it a good rev or it just chugs and cuts out.

Any help would be great.
