proper way to shut down engine

[Hank Jarrett]

I have the original its the stock knob off the tank, I'd like somethin on the dash to turn off the fuel flow

The original IS the one with the rod to a knob just under the panel. You pull the knob to rotate the valve and shut off the fuel. Taylorcraft NEVER built a plane that required you to reach down under the panel up by the valve near the firewall.

if I put a new valve on below the tank and run a rod up to the dash for control, I would like to add a bracket on the tank to hold the valve so I'm not putting stress on the connection to the tank

I've seen another that had the lean mix knob, with a cover, but that knob only works at altitude,

yah mine has the original knob, it runs directly down from the tank, I think I can make a rod assembly that will run up to the dash and turn to open and close it, I kinda have it in the winter to do list, I want to drop the tank and have it worked on, I also don't want any undo stress on the tank fittings don't need anymore leaks.
and for the fuel shut off to kill the engine, I was thinking of a valve right at the carb
does any have a video of the carb removal for the c 85 i can't get to the last nut on the carb, been looking at the 2 nuts on the manifold and the hose connections, but really would like a conversation with someone, 501 519 8066

that is not a legal modification. It needs to be done per original

Original looked like this but there are several different ways around. fuel clip.jpg

Reminder that there is an AD requiring a guard over the fuel shutoff .

Dad was taught to fly by an old timer who was flying before WW2 began, and was a CPTP and civilian B-26 Marauder instructor. He was taught to turn off the mags, throttle full open as the engine shut down, then fuel shut off.

yeah I like the idea of shutting off the fuel, but the fuel valve on mine is at my feet, so unless I install a valve at the carb or somewhere between the tank and carb with a remote shut off I'm sol
but with winter here it might happen

you should have a rod and knob that runs up to the panel. I should have some rods extra

You need to correct that! The valve is up by the firewall under the tank on a Taylorcraft but there is supposed to be a rod attached to the lever that goes back to the bottom of the instrument panel. In an emergency you NEED that shut off to be available.

First, find a mechanic familiar with small continental engines. You can shut it off with the mags all day long, no problem. Personally, if I have a stromberg, I will shut the fuel off and let it run out of fuel. This prevents the constant drip of a needle and seat improperly set, or leaking. Mixture on stromberg doe nothing below 4500 density altitude.

[slam555]

well that answers that, again can't fully trust the A&P's with the exception of opening the throttle after the mags are turned off I was doing it right.
I really wish one of you guys were in the southwest MO area

What's important, Slam, is to understand one* of the reasons why piston engines need a lean mixture to close down. The last thing you want in a shut-down piston engine is unburned fuel in the cylinders, which might wash away the protective oil on the cylinder walls.

Some engines use the mixture control to starve the cylinders of unburned fuel. These use the "lean" mixture so to do.

Our old Strombergs don't have that pleasure. The only way to purge the cylinders of unburned fuel is to smartly open the throttle after the switches (mags) are turned off, with the engine rotating to purge the cylinders of excess fuel.

*it's not the only one.
