Default Can't get buggy to idle without engaging clutch

I can't get my Sportwerks mayhem to idle without engaging the clutch. If I set it too low, it will die. Is there any clutch adjustment or something? I read the manual and you can set the clutch shoes 2 ways and I set it the way where it won't engage as hard ( trailing ).

Your clutch bearings might be ceased up, or your clutch springs might have a problem. Whatever the case, your clutch is dragging when it shouldn't be!

you need harder springs.

try mugen seiki springs 1.0mm thickness if you are using plastic clutch shoes, or 1.1 if you are using mugen seiki alluminium clutch shoes.

How do install the clutch because I can move the clutch shoes in and out when installing them. Should the clutch shoes be inplace until enough centrifugal force pushes them out?

The spring has a long, and a short leg. The long goes on top of the shoe, and the short has to be forced behind the clutch nut as you put the shoe over the flywheel post. If you don't have a clutch spring tool, it can be difficult, but you can do it.

or you could buy a losi clutch and then it's super easy, plus with a 4 shoe clutch, you can experiment with different combinations of shoes and springs

Also, you could buy the mugen clutch shoes and spring, it's set up kindof like a 1/10th scale truck clutch. the kind with 3 shoes and a wrap around spring.

BEHIND the clutch nut or in the clutch nut groove?

clutch nut grove, but make sure it's on the side of the nut so it applies pressure to keep the shoes compressed against the nut. It should be pretty hard to pry them up by hand. the force produced by the engines RPM's should fling them out when your on the gas.

It's like one of those rides at a theme park that looks like a huge circular drum, you get inside it and it starts to spin really fast, causing you to fling to the side of the wall making it hard to lift your arms/legs or head. This is kind of how a clutch works, when it stops spinning really fast it's easier to peel your self off the wall, that's what the springs in a clutch do, they retract the shoes to the center when it's spinning slowly.

does this help?

I just ordered some new clutch springs. I think my clutch springs are messed up or something because I can swing the clutch shoes in or out when installing them. What you guys are saying is that the springs should hold the clutch shoes in place until enough centrifugal force causes them to swing out to grab the clutch bell right?
