i took the 400 scrammy for a ride yesterday and it ran so bad it wouldnt even pull back on the trailer.i put 2 new plugs in it but it never ran good all day.i thought it just fouled the first 1 but it didnt run any better with the newest plug either.crapping out and never cleared up.this was the first ride in over a month.it ran fine last outing....any ideas or suggestions would be helpful!..mark

 

Did you change/clean your air filter?If so you could have gotten some bad gas.

 

has it been sitting for a month before you rode it without anything done to it u might just want to open your carb and clean that and maybe even you fuel lines. my suzuki does that to me sometimes if i dont ride it for a long time it wont run very good usually ends up being debris in the fuel systems that settled.

 

well did u happen to change anything in the carb like the jet needle because when i adjusted my needle i didnt get the plate the sits over it down in the slide like it needs to be and it would run but it had no power it just stuttered alot.
