I know this has been debated to the limits of understandability, but I found the cheapest/easiest fix is to make the fuel line as short as the pipe pressure line. Keeping them as short and equal in length as possible. This is not exclusive to the Savage...
Forgive the noob question, but what do you use to clean nitro off of the composite brake discs? (Savage X 4.6 rtr)
During break-in the brakes were covered in oil from the nitro. I am not sure of the disc composition and didn't want to use anything that would destroy them.
