How does Throttle Assembly Work?

Recommended Posts

Hi

quick question on how the throttle assembly works on a 1990 RM125. 

Is there supposed to be a return spring in the assembly?


Meaning if you increase the throttle by rotating the grip clockwise and then release the throttle grip, should a spring turn the mechanism counter clockwise reducing the throttle?

Or once you move the throttle to a position it should stay set until you move it. 

thanks for the info.

There is a throttle return spring inside the carburetor, item #20 here:

Apart from a weak or mis-installed spring, if the throttle does not promptly return when you release the grip,

it can be be caused by a frayed/worn/dry/improperly routed throttle cable or, a damaged throttle tube assy.

Considering this is the first time I have assembled a carb I will go with I probably screwed up. 
 

I know it’s difficult but does this look right?
