Fuel starved under heavy braking

08 Husky 510 SMR

When the tank is a little over half empty the engine stumbles and sometimes stalls when I get hard on the brakes. WTF. It seems as though all of the gas is moving to the front of the tank and starving the fuel pump. It's been doing this for a while now. Any thoughts?

On the brakes you shouldn't be using enough fuel to starve it, I'd think. Is the float on the carb set too low?

Is it carburated or fuel injected?

Aha!! Ok I got nothing..

Seriously though. It could be possible that the gas is moving around so much in the tank the the fuel pump is starving? Not sure. Check out cafehusky.com. They know everything Husky there and they will more than likely help you out if you have any questions.

edit:

if it has not been having these symptoms its whole life, there is probably another problem.

if it has, and youre just now noticing it; i would try and keep the fuel from sloshing and see what happens. ie:

fuel foam, fuel baffle, semi-sump in the bottom of the tank, etc

I figured it out. Husky specific problem that I thought I already fixed but had to redo. Thanks for all the input though. This is why I love forums, because even a mechanically declined person like me can diagnose a problem in 20 minutes.

The fuel pump on the Huskies is held in place by...wait for it...a dinky plastic clip with no locking mechanism and a fine Italian zip ty. The fuel pump slips upward making a bike with a half tank of gas act as though it has no gas. I fixed this the day I got the bike so I had completely forgotten about it but apparently a permanent fix requires additional zip ties to be fastened vertically around the fuel pump and not horizontally.
