So i have this kart ebr, it broke on me but i finally got the parts i needed and got it going but now i getting issues with what i think is the hop up. I am only getting half of the fps i should be and the bb's just go out and dive bomb at about 60ft. I've looked high and low for air leaks and i am confident when i say i see no leaks. The hop up unit is put together properly and it should work, the only thing that I have changed is the bucking since it first broke and i no longer no what has become of said bucking, im thinking it may be from the mesh between the stock rubber and the air nozzle. Does anybody know of anything that would cause this issue?
