Put at least 400kms on the machine in the last week. Tried starting yesterday, started long enough to unload from pickup. When i tried to restart it would not go. Pulled the plug and primed machine by pouring gas into the cylinder. It starts but will not stay running?

Any thoughts?

Check and make sure the pulse line on the fuel pump is not loose or split.

Crack the fuel cap as well and listen for a hissing indicating a plugged vent.

Just another thought, did someone turn the fuel shut-off valve?

DOES THAT HAVE THE DESS KEY IF SO MAKE SURE ITS TIGHT AND CHECK GAS FILTERS.

What are the conditions outside? Is it very cold? Could have a bit of moisture in the fuel and the fuel pump could be froze up. A pan of hot water does the trick.

if the fuel pump is froze you can tell because before your sled stalls it starts to rev really high. you can put as much gas line antifreeze in the the tank as you want and the water will stay in the fuel pump anyway. you have to take it apart and clean it with wd40 or more gas or something. if you have it apart you can telll if maybe your pump is shot as well

Do not take the fuel pump apart. Just pour hot water over it. Nothing more required if it's ice causing the problem.

How many miles on the sled? I had a 700 twin that would not start because of low compression. There was not enough vacuum from the case to move fuel through the fuel pump. The 800 twin does have ring problems. I would check your compression, this would be my guess if the the compression is too low.
