FIX for engine that won't rev down.

[skizman]

This is for a chinese round barrel slide carb. My engine kept staying revved up, and after my second carb, I found a great fix. It's how the spring is placed inside the slide piston. On the end of the spring there is a wide portion and a thin portion where the spring has it's last coils. The throttle cable runs down along the inside of the spring into the slide piston. The cable will bind up if the spring is inserted the wrong way. My rhino never ran so good after I found this fix.
The picture tells it all.
