Need help...My 2002 scrambler 400 4x4 has no power out of the hole,it just stalls but when I get it rolling it screams. it really sucks when I stop on a hill and try to take off.I am running a 260 main and I dropped a size on the pilot jet,and played with the clip still nothing still boggs at the bottom....could a change in clutch help???like a different spring or weights...thanks for any help[img]i/expressions/face-icon-small-confused.gif[/img]

 

Did you do a plug check ? If not that should be the first hing to look at.Then you can go from there.If the plug checks out ok.You may want to check the tension on the secondary and or the secondary buttons.
