no you just take the snorkle. the hose lookin thing that runs up from the lid

 

heres what u do on ur carbs there are air and gas screws and if one is of it will prob make it back fier and run like $hit only on one side . and for it air take the lid of ur air box and drill about make 9\16 size holes about 4 on top move down about an inch and 4 more hole and u should be set

 

The guy befor me cut hole sin the airbox lid..just like you said..I turned each air screw out 1.5 turns..If it had bad reeds would it back fire?as for the gas screw? where is that located on the carb? inside or outside?

 

my bad i think the air and gas screw are thed same thing atleast thats what i was told so that screw determins how lean or rich u run it

 

for the reed thing take them out both of them and soak them in gas for about 2 hours and then spray some card cleaner on and when its spotless put it back it. it couls also be the left side of ur wireing that hooks on the spark pulg if u know how to cheack that then that will tell ya

 

i looked on a site and it said the (neddel piston) should be on the 3rd i have no clue what that mean but if one carb it different then the othe it will deffenlty do something

 

What kind of air filter do you have (K&N or Foam). This will make a difference in your jetting. There has been alot of quessing going on. Try to only do one thing at a time. Your air screw will not adjust the backfire out. Go through your carb completely.

 

Ill try doing that with the reeds and see what happens..
