welcome to Miniriders,

have you tried turning the idle speed screw down?
or checked that the throttle cable is seated correctly into the top of the carby.

cheers, craig

 

[lynz2017]

yes have done both, ive been told could be to do with the wiring being wrong is there any pics of how it should be wired?

 

[lynz2017]

anyone? need help asap even a picture of someones posted up showing which wire goes where would be so grateful

 

[my67xr]

there is only one wire that comes off the engine, it connects to the kill switch then back to an earth

 

[my67xr]

have a look at the top of the carby,
is there a rubber boot where the cable enters the carby?
if so slide it up over the cable a bit and there might be an adjuster there too, back that off and see if it helps you.

Does it get worse when you turn the bars left and right?

Clutch adjustment? Is it doing it like this....this clutch was not adjusted and I had no kill switch hit first gear and it was off....and I was like oh dear think quick!! Adjusted the clutch and fitted the kill switch and it was fine after that, no more unexpected rides!!

this is a little 2 stroke mini quad yeah ?

Yeah, mine does the same, ours is a 125cc Elstar dinosaur..... I think we need a new carby for ours, as when u adjust the idle speed screw down it stops trying to run, but then it won't idle either.... Their doesn't seem to be any happy medium.

Its a 2 stroke mini quad yes but it has an ignition also so theres 4 wires, how do i adjust the clutch? The carb is brand new

 

[my67xr]

can you post a link for me, to show which type of quad it is please ?

the clutch on most 2 stroke quads isn't adjustable, it's centrifugal, so it only engages as the revs rise.

did you check that there isn't any adjustment on the top of the carby where the throttle cable goes in?
even a couple of pics of the quad/electrics may help?

is it electric start?

but the electrics wont make it idle high.

 

[lynz2017]

no its not electric start but has got an ignition its pull start

If this is not the throttle cable too tight or high idle, it has had a clutch spring step off or snap!

 

[lynz2017]

the clutch is fine its brand new

 

[my67xr]

ok, i have played with a few of those quads
the ignition is internal,
all it has is a coil that is fired with the magnet in the flyweel, same principal as used in a lawnmower.

what was your answer about the adjustment on top of the carby ?


if you turn the top adjuster back into the carby top,
then back off the idle speed screw on the side of the carby the idle speed will drop

 

[lynz2017]

which wires go to which though? under the rubber bit its just a metal gold bit

 

[my67xr]

so is it a threaded adjuster with a nut that locks it to the carby top
or is it just a tube sort of thing ?
can you post a pic of it ?
