So i bought this 96 Ski-Doo mx z 440 l/c sled from a guy last weekend for dirt cheap because it was having issues and he didnt wanna deal with it. found out the pick up tube in the tank had fallen off. Not a big deal, fixed it. The sled starts now and runs but bogs and dies shortly after. For the record the carbs have been completely gone through and cleaned....just eliminate that from the list of possibilities as to why its bogging. Now to my question. keep in mind when i purchased this sled half the thing was in pieces. Anyways i got it all put back together. At first i couldnt , for the life of me, get the fuel lines to fill with fuel. Figured that out, but in the process i pulled off the vaccuum line going from the crank case to the fuel pump to see if there was any vaccuum and it was blowing not sucking. Sled still starts and runs though. I could b mistakin but isnt it suppose to blow instead of suck??? Next question, do the oil injection lines on the oil pump need to be bleed or will the oil just naturally begin to fill and flow from the pressure? Im hoping this all makes since and that one of you master minds can give me some insight to what might be happening here. I'll try anything to get this sled running right!!!!
