Incorrectly tuned MGT 4.6?
I have an MGT 4.6 and have set it up (wrong?).
It runs rich with blue smoke, accelerates well and has some good speed but when I brake if I (even slightly sometimes) tickle the brake the engine stalls.
When the truck idles it doesn't change and it doesn't splutter accelerating its just slowing down that is the problem =/
Help

Check to make sure your linkage and idle gap are set correctly. Pull off your air filter. When you look at the idle gap in the carb at neutral, make sure it doesn't get smaller when you apply the brakes.

Well first you are going to adjust the idle gap with idle adjustment needle so the carb can't get any smaller then what the car idles at. Usually about 1mm open. You also may need to adjust the linkage. You manual that comes with the truck should explain this. If you don't have one, on Team Associated website I am sure you can find one there.

I did try using the settings from the manual but the same thing happens =/
I'll carry on annoying you some more tomorrow if it still stalls and the whole is small
No look =(
The whole shuts no matter how far I turned the LSM =/
It even got to the point where I had to run after my car to turn the screw back.
I noticed that when i tickle the brake, the servo locks up into brake and shuts off the accelerator to the point where the servo rod actually flexes :S
What the hell is happening lmao.

Still cutting out; when the car idles the carb gap is about 1 mm but when I apply the break it closes up, to get it to not close up I have to turn the idle out the the point where I have to run after my car to turn it down again - lol.
Or, I could have used the brakes but that didn't occur to me at the time 0.o =/
Anyway... Could this have anything to do with the other needles?
If so which 0.o

It still stalls on braking 
Not fun to not be able to stop without cutting out =/
Everything else is perfect, it just doesn't brake =/
Could it be worth changing the stoppers on the servo so that the brake engages before the idle hole closes?
