Hi I'm an RC Powerboater and need a hand. I bought a used OPS 3.5 Rally motor (D-shaped rear exhaust) and need help or ideas how to set up the throttle linkage.

I've never owned a slide barrel carb before nor owned a glow-powered car and don't know how they are hooked up to each other. Is it just a straight shot from the servo to a ball cup on the carb? What keeps the barrel from rotating? The slide barrel just floats inside the housing from what I can see. Is there plastic assemblies built into car chassis that is common for this? If so I would like to know where a clear picture can be found out of a manual online or if someone could scan and post a pic out of thiers?

By the way, I can't find a 180 degree header yet for this so I need help where to look.
