My buddy has an 02(i think) wolverine and to get more power he removed the airbox lid (aslo with a W.B. exhaust, it's jetted accordingly and runs very strong) Only thing is that with the lid off; gas spits out the carb and gets the filter wet with gas. I'm not too familiar with the vacuum controlled needle jet this machine has. Anyone ever experience this before, Any tips on this carb/machine are much appreciated. Don't want to see what happens if it would backfire out the intake....
