Have any of you guys tried using a Novarossi Carb on a Sirio Evo 3? Im having a few problems trying to get the Sirio Carb to fit and function cerrectly in my MTX4. It's a very tight fit. I've had to dremel a little from the carby under the midrange needle so not to touch the brake disc and also, the slide hits either the top deck or the fuel tank when the throttle is at around 3/4 open. Also, the rubber boot on the slide gets caught on the topdeck when i open the throttle
