Throttle Return Spring for H1 and HS2 Carburettors

Description

There is only a throttle return spring on H1 carburetors.

On HS2 carbs, there is a throttle return spring, and there is a separate choke return spring. These springs are so similar, it is extremely difficult to tell them apart. Because of this, it is very common to have a choke spring where the throttle should be. The choke spring is slightly larger, so this will cause weak throttle return. If in doubt, we now have choke springs on hand, which you can find by clicking here. 

The throttle return spring is different for H1 and HS2s, please make sure you get the right one!
