only on hills can pull whatever pull over down trees thats ok problem is only on hill coming up with the front up higher then the rear

 

well i had to take it to the dealer and the mech. there adjusted the float up alittle and its alot better but still needs to be adjusted alittle bit more it doing alot better but on really steep hills it still runs out of gas ........its a step in the right direction

 

well i made a second float adjustment this time did it myself and the 4oo is running like its been hit in the tail with buckshot pulling the hills like its mad at them thanks for all the tips ........

 

ya if the float isnt correct on the hills it will loose power for sure from lack of fuel flow. glad you got it figured it out.

Sounds like the float level is too low or you have a bad float in in the carb.
