Default Remote Needle valve question

I recently built a bearcat and used a nice Super Tiger 40 I had for a powerplant......Ok the motor has the original need valve coming straight out of the carb......I wanted to have it all "IN COWL" so I added a second remote needle valve back in the plane. I didn't want any holes in my cowl except for the 2 pipes out the bottom....I want to use the remote needle to adjust my motor, but what do I do with the original....turn it all the way in?....or out? or does it matter? I need help

You definitely want the valve at the carb fully open so the remote needle will do all the fuel flow control. I would also put a snug piece of fuel tubing on the carb valve to make sure it doesn't loosen up accidentally. Actually that works great for any high speed needle valve.

Either cut off the tapered part of the original needle or wind it all the way out. In both cases leave enough of the threaded portion in the sleeve to lock it with the collet or as mentioned with a piece of tubing. If you are truly motivated search the industrial suppliers of fasteners and purchase the appropriate size socket head cap screw to screw in place.

Here's a cheap remote needle assembly that works great. Have used them for years.
