Firstly I'm new to the nitro rc's just got myself the losi 8ight and want to get into the whole racing scene. When the buggy is at idle and I accelerate it is very sluggish would that mean the fuel mixture is to rich or to lean? Or could it be something else? Thanks

Bogging down indicates it is set too rich. Did you complete the engine break-in? Onceyour engine is broken in, you'll want to lean it a bit as the factory settings are rich.

Richen the HSN up a little, then lean the LSN until it takes off good. You will need to lower your idle speed afterwards. Make sure you set the linkage properly with the idle adjustment screw. if you don't it will make tuning difficult. The Mach 427 is a very simple engine to tune. Try to keep it under 240F, they will vapor lock at 250F.
