I seen this on a NEW Axe Rossi Mamba X1 this week a friend got from Me and Casey NEW he Green Slimed the LSN and the HSN and Bottomed them out and reset them to Flush but it had MESSED up the LSN and HSN it ruined his Carb and now he needs a NEW Carb.
We took a Carb from Casey's Axe Rossi Mamba X1 the LSN and HSN have never been Bottomed out he just started tuning from Flush and put it on Russes motor and it Ran GREAT so we found out you NEVER NEED TO BOTTOM OUT YOUR NEEDLES ARE YOU MIGHT RUIN YOUR CARB.
yeah, even if the manual says 3 turns out from closed, trust me the least little bit will mess up the spray bar, you can still pull the needles out and green slim them but make sure when u reinstall them into a axe rossi carb to put them to flush and start tuning from their. if u have ever even lightly closed the lsn on a axe carb then u might as well order a whole new carb, i no this sounds crazy that even alittle bit will mess it up but trust me it will, it wasted 2 practice days for me. when ever u get a new motor figure out a way to count turns out from where the factory set the needles so u no a good starting point on both the hsn and the lsn so u will never have to worry about flaring the spray bar or bending a needle, i barely turned mine until it stoped on the lsn and that is all it took, these motors are made to such exact tolerances that it takes just alittle bit to screw them up and then u think u got a bad motor. most of us have had a tmaxx with a 2.5r and on those carbs they have a built in stopper to keep it from bottoming out the lsn(u can read it on the website) and that is where i think alot of people are messing up, cause alot of us racers learn something and it is imprinted in our mind. guys i hope this helps thanks to chris and casey for the help and to axe rossi for being willing to make it right with me.
