How often should I check the carb settings?

Check the low and high needle settings after the first few runs and then periodically when conditions change; small adjustments help maintain consistent throttle response and economy.

Are there common chassis mods needed for fitment?

Most 1/10 off-road chassis accept this engine with standard mounting, but you should verify manifold angle and exhaust clearance to avoid interference with bodywork or suspension components.

What glow plug type works best here?

Use a glow plug recommended by O.S. or a high-quality equivalent matched to your fuel and local temperatures; this helps the engine run cleanly across the rpm band.
