Proper throttle set up for no interference
 

I was told that I needed to change my throttle set up and I agreed
so I am changing it but, I was wondering has anyone else heard this potential problem !!
I am setting up a solder type throttle cable assembly made by Du-Bro and I was told at the (carb)engine connection to made sure to use a plastic
quick link that attaches to the carb arm that a metal one can cause interference because the hole set up is metal . The plastic
part in the package does not fit my carb ...

thanks David

Hi David,

What kind of engine are you talking about? That problem usually only occurs with engines with ignition systems. Glow engines don't have that interference problem.

Hi David,

We used to worry about metal to metal contact a lot. It's OK if the metal was tightly bolted together like a metal screw holding the engine to the mount, but a metal quick link to a metal throttle arm was a big no no and would just about guarantee radio interference. Doesn't matter what sort of motor it was the vibration. It doesn't seem to be such a problem with modern radios but I still wouldn't risk it.

A nylon quick link should fit straight on the throttle arm.

The ignition interference is a different thing.

Yes, anytime you have metal to metal vibrating you can get electrical interference. 2.4GHz is more immune to this type of interference than the 35, 50, 72 and 75 MHz frequencies are but can still be effected. It is never a good idea to permit any metal to metal intermittent contact.

It's a gasser if I remember correctly.
Install a ball on the throttle arm and a nylon link on the pushrod.
They come in different sizes to fit the throttle arm hole and the control rod/threaded adapter you have.

If it's for a gas engine install then it's safer to use a bolt on swivel type ball link rather than the plastic snap on type because the increased vibrations from a gasser can caused the snap on type link to pop off the ball.
