The gold is the low speed. The needle you're pointing at is the high speed. Do you know how to fix an idle issue with that engine? Cuz after I broke in mine, the idle is flat but too high. Mine runs well, goes at least 60 MPH, but the idle is horrid. Might as well get an RB Concepts Circuit 11. That'd be worth it.
Hi there, I have a question you may be able to answer. I have this exact model, the ST US Sprits 2, the engine ran in perfectly, but soon after started overheating very quickly. It would reach 250F after a few minutes of easy running. Also it jumps from idle to full throttle, without the carb slider moving. First I thought the radio system was moving on its own but I disconnected the servo horn to watch it idle and it still happens. Have you any idea what could cause this?
yeah dude mine wall stalling up and was kinda bogging i pulled out the LSN and sure enough the small O ring was fuct....just put some silicone round it with a bit of luck this will fix all.....Well picked up
and also didnt u say that its to rich on the low speed and leaks in to much fuel and stalls? So why at the end of the clip did u say that if its is bogging to richen the low speed needle!
what you say is the LSN is really the middle speed needle. reason there is problems is u must be professional to mess with it! i blew my engine!

@2606259 sounds like your running very lean, rotate your high speed needle an 1/8turn counter clockwise and see if that helps

@Paxmax I you got that right. After much persistence I have up fuck this hobby.
This hobby would be good if you can afford petrol models like the Baja but no more nitro fuck that.
