When I was re jetting my carb I noticed that it is missing that little plastic part that goes under the main jet and where the pilot jet is. I only noticed I didn't have one when I took apart another blaster carb and it did have one. So my question is, do I need that part? It was running great with out it when it was fully stock so I didn't bother trying to get another one. But since I have the carb off I wanted to find out if I really need it. And where I can get a replacement if I need to.
