What happens if your carburetor is too high?
If fuel is leaking from the carb, it can potentially cause a serious problem – fire. If the fuel height is too high but the bike is running, the engine will have a tendency to display a rich running condition, which will make the throttle response slow and the engine note muffled.

When to know if your carburetor is running lean?

Why does my bike feel slow at low rpm?
Starting with carb’d bikes, it’s fairly simple. An engine running lean at low rpm tends to feel snatchy and unpleasant. It’ll also need lots of choke and take a while to warm up. If it’s too rich it feels slow and fluffy, as if it can’t be bothered to rev, or for the revs to die back down again.
