1980 Scorpion Whip 440 - Walbro WF Carb Issue
My 1980 Scorpion Whip 440 Wlabro carb is givng me a hard time (again). The idle mixture screw on the Walbro carb needs to be turned out at least 3 to 4 turns for the sles to stay running smoothly at idle. The idle speed also needs to be set high at 3K RPM. Then when you're ridng it will be going along fine and then she starts to die until you feather the throlte and then she runs fine again for a few more minutes until you need to feathe the gas again. Seems to happen more when going up or downhill. The sled also acts like ti wants to stall when the sled is stopped quickly. I pulled out the fuel pickup tube under the fuel pump and cleaned the 3 holes in the tube and the 2 air bleed ports that are under the fule pump, but the problem remains. Anyone have any idea where the carb may be blocked up?
P.S. Tank was cleaned and filled with new gas mixed at 40:1
