Go kart won’t stop running when I start it

[Fanisswag]

I have a dhv 6.5 electronic ignition engine on my go kart and when ever I turn it on it starts running. I was told that it could be my centrifugal clutch.
Can anyone help me

Is your idle speed too high? Have you removed and inspected your clutch?

 

[Fanisswag]

My idle speed was too high and so I lowered it. I am trying to remove the clutch but it seems like I can’t.

Check for set screws. Or bolt in center.

At the centre of the clutch ?

 

[Denny]

Around shaft.

While you're messing with it, take that sheet metal loose from around the cylinder and clean that pine straw and stuff out of it. It's not meant to be a heat shield or guard, it's to funnel airflow from the cooling fan to pass around and through the cooling fins of the cylinder. Stopping up or reducing that cooling air is something you'd regret when it gets to be hot weather again.

could it be a broken spring inside the clutch? its happened to me a few times in the past

 

[Denny]

He has to get the clutch off first though.

 

[FlyFrog]

well if he gets the bolt out on the shaft there should be a c clip and he can take the drum off and check

Take the bolt out of the crankshaft (I believe it’s a size 15 hex head) hold the shaft with some vice grips clamped onto a paper towel and then loosen it. Frog is right, the c-clip can be removed and clutch inspected. Sometimes not worth messing with, can alway buy new one for $15 if it is beyond saving.

Have you got proper snapring pliers to get that out and back in, or are you planning on doing it with scratch awls and visegrips? Here's what a decent set with small enough tips looks like, I got them just for gokarts work, you should too in the absence of having a proper set..............

It looks like there is a good bit around the cover over the flywheel and mag. Would be a good idea to clean that off too. No airflow means no cooling.
