Bundy I have found this before but not really sure what causes it.
At a guess I would say if you don't have your carbi slide in line with
your servo & throttle linkage (linkage pulling at a angle,the amount
of pulling & closing could wear it internally (maybe)
The air induction hole in the slide can get a slight bur around the
lip of it.
I just use some fine (1200) wet & dry around the opening
on the slide, top/bottom & you should be good to go

Cheers Darren

Hi Darren

Thanks for the advice, I did a Blis trick and used a rubber band to pull the carby shut and it seems to be working okay at the moment.

Aint no trick, it's solid advice handed down to me by many experienced runners..

But anyways...

Brother, check that the angle of attack on the ball and servo is inline with the idle screw. the Idle screw runs in a slot and if the servo is pulling at an angle it can stick WOT.

So, loosen the small hex on the carby ball "thingy" and rotate it until the carby opens and closes in a straight line while throttle via radio and throttle servo.

And have a happy Xmas day, same to Abby, Richard and family.

yup and now it's magnified with plastic carbs.
mine moves freely but I had to get a high torque servo for it. a standard servo isn't strong enough to close it all the way returning to neutral.

Thank you, Christmas wasn't too bad...

This was on run in bench that I was having an issue with. This linkage came off, so I went in to close the carby and put the linkage back on forgetting about the prop
