Engine quits after landing /braking

Having a problem with my RV6A, Lyc 0320
After landing and applying brakes engine RPM drops below normal idle and will stop running if I do not open the throttle.
I have adjusted idle mixture but problem still occurs.
I am thinking float level. Electric facet pump is on during landing.
Carborator is a rebuilt MA-4SPA
Standard Van's airbox and control cable mounting.
Anyone else ever have this problem.
Thanks,

I think you're looking in the right direction with the float, FWIW I do not use the Facet electric pump on landing... never have as the manual pump pressure is verified on the FP instumentation as part of the landing check list. The carb is easy enough to take down and check the float for saturation, adjustment level and or a defect.

Also, make sure the 4 nuts are tight on the carb. If loose, the carb will tilt forward during braking and suck enought air to make the engine die.

Engine quits

I had what you described in your post. After going through a process of elimination what I discovered was that my PRIMER PUMP was faulty. I disconnected it totally and no problems since. Good luck.
