Default Left hand throttle

I have a 1996 RV6 360 A1A CS prop and want to set up a left hand throttle. I have read several threads on the topic where a few builders have done this successfully but need some advice from the community on the below options:

1) Connect additional throttle cable on inside of throttle arm
Clearance between carb throttle arm and carb bowl is 0.5950" If I add a rod end bearing and a washer that will be 0.4750" leaving a clearance of 0.1200" ........ this could work but would not leave much clearance. Does you know of a standard or best practice when setting this clearance?

2) Connect additional throttle cable on same side of throttle arm.
This requires putting 2 rod end bearings together. Solves clearance problem but other applications have put each rod end bearing on each side of the throttle arm.

3) Get a new throttle arm with more clearance.
I have a precision motive carb and not sure if I can buy a different throttle arm.

Any thoughts or help appreciated.

Fly from right seat. That's what a friend of mine does.

My -7A was designed to be flown from the right seat - right stick, left throttle. You could fly yours from the right, but I'm guessing the all instrumentation is biased toward the left seat.

Would it be possible to mount a throttle on the left side similar to the RV-8, disconnect the present throttle/cable installation and replace it with another?

Although this means that your pilot passenger won't have access to a throttle, but "needs must" as they say across the pond... (;>0)

I have a left hand throttle in my -6, but was able to use the standard push/pull mechanical connections on my Marvel Schwhatever carb.

I put a left throttle in my RV6 when I had it. I disconnected the center mounted one and tied it back clear of the engine leaving everything aft of the firewall in position. There will be too much friction if you try to leave the original throttle cable connected to the carb. I left the original cable installed in case another owner (was planning to sell when the project was complete and did) wanted to revert to the original configuration.

You could fabricate a system with both a left and center throttle that are bussed together but it would be a great deal of work for very little reward. Those flying with you from the right seat do not need the throttle much for flying around. Seems most of the "Hey, you want to fly for a while?" flying is at cruise when the throttle does not move. If you plan to regularly have a right seater land or fly formation, you have more of a case to do the extensive work required to have dual throttles but that is very rare.

Paid through 2018! How about you?
