throttle routing-4 stroke
Hi all;
I'm getting ready to swap out an OS61 for a Magnum 91 4-stroke in my Tiger 60. The carb is behind and in the middle of the Magnum. That will place it close to the firewall. Since the throttle arm is in the center of the engine and close to the engine's body, I'm looking for a way to rout the pushrod. The fuel tank is located in a compartment directly behind the firewall, so I have to come out near the fuse side. I've installed a Saito before by bending the pushrod back on itself to attach, but this one doesn't look like that will work. Suggestions?
Thanks!

CB36. If you do as Minnflyer suggests, be sure to put a piece of insulation over the wire so that you do NOT have metal to metal contact. I used teflon tubing for my similar system.

But yes, if it's metal put a piece of shrink tubing over the wire.

Can you explain how I go about this? For some reason, my brain is not wrapping around this concept.
Thanks!!!!

If you have a metal throttle arm, you must use something plastic for a connector to the throttle arm to keep from producing RF noise.
Or you could use a plastic control rod

OK, I understand the RF thing, but how does it get in to the system? The problem is I have very little room in front of the firewall. MinnFlyer's drawing will work, but there will be metal/metal contact with the bent push rod and the throttle arm. A ball link will have to come in from the rear and there's not enough room. The carb on this motor is smack-dab in the middle and I can't loop forward to connect. It has to come in from the side or rear.
How about cutting the music wire push rod and inserting a nyrod somewhere in the middle? Is it the actual interface of the metal rod and the metal throttle arm the problem? I was assuming that the noise would transfer down the rod to the servo and get into the radio that way. It would seem that the plastic servo arm would isolate that if this was the case.
