When he starts to go the sled dies like it ran out of fuel. But it then starts rite back up. I put all new gas line on even in tank.But i did not change the line from the crank case to the fuel pump.and I cleaned the carb.
 

Those carbs are finnicky and very sensitive to the adjustment screw. Play with the adjustment screw, try 1/4 turn out, then retract in 1/4 turn increments until it works. Make sure that you start with new sparkplugs.

To engage sled with maltuned carb, try giving it a little choke while trying to engage, add throttle SLOWLY (don't just punch it and hold it) until the engine speed has increased *significantly*, then start "blipping" the throttle to speed it up more.

Make sure that the engine is warmed up fully.
