does a minibike twist throttle already have built in springs?

[azndude3141]

if no, then how would i attach a spring to the engine to return it to idle everytime i let off the accelerator. im a little confused. (yeah, im a noob and this is my first build, thats why im asking a question like every 10 mins. lol)

oh and as always, THANKS FOR YOUR HELP!!! :smile::wink::smile::wink::smile:

Put the return spring at the engine/carb and make sure it's enough. :wink:

ok se in the pic were i circled it thats a spring that runs off of the accelarator carb. i ran a srping from the accelarator on the carb to a custom bracket i make then i used a hose clamp and clamped the one end of the bracket to the exahust and then drilled a hole in the bracket put the one end of the spring in the bracket and the other running to the carb it works like a dream and retrackes perfectly it took 10 minutes to make and 5 minutes to adjust it and the bike idles and the throttle retracts PERFECT hope this helps

i understand it now, what you did is you got a bent pice of metal, connected the spring to it, and then clamped it to the muffler with the spring. OK thx a ton!!! :smile::smile::smile::smile::smile:

You don't have to do it exactly like that. That was just a pic. so you would get a clue.

What kind of engine are you trying to hook your throttle up to. Randy has a post how to hook up a throttle for Tecumseh started and theres pics for the clones also out there. I have Tecumseh's and clones throttle set ups in my photos also.

If your running it with the goveroner still hooked up the throttle cable goes to the bracket under the tank

Even if there are/were throttles made that would retract on their own, does not guarantee that the carb will slam shut. Scott.

71 Dodge does it exactly like me.

I have run the throttle cable through the spring,it is a pain to get the cable into the clamp and tighten the screw with the spring on the cable but it does work very well. use a small washer if you need to stop the spring from sliding over the cable.
