I own 5 Traxxas nitros , to turn if off, hold your finger over the exhaust tip , make sure the engine is up to temperature before making tuning adjustments, always start with the high speed needle first , your idle is high because you need to adjust the idle screw, your carburetor gap is too wide
I bought the same slash in the same color about at the same date as you. Also came with the same “problems”. All you need is adjust the low speed idle after the brake in and you are good to have fun. I’m super happy with my slash. I fucking love it.
I have a Jato 3.3 with a modified engine, Revo 3.3 with a OS .21tm, Nitro Rustler with a Dynamite .19, and the Rustler 4x4 BL-2S electric. All are fun in their own ways! I like the electric for the low noise level, but I’ll always have a soft spot for nitros. I always wanted to get the Nitro Slash, but I ain’t got room anymore :)
Gas and Nitro are real men’s RC. Planes helis and cars. Electric is cool and has its place. Great for kids but Nitro and Gas is where the fun and beauty of the hobby is.
Idle speed needle, then high speed needle, then low speed needle adjustments. In that order. In wards is leaner, out wards is richer. Leaner equals more throttle, too rich and it will bog. Prime it by turning over the engine with you finger plugging the exahust. Hpi has a good how to tutorial on how to tune their savage. Worth the watch. After run oil is essential. Drop a drop or two through the carb and turn over. Thats the essentials
Dont need to pour the fuel in like that u can squeeze the fuel bottle, push the nozzle into the fuel, and then release it .Hole fuel up into the bottle also u should prime the car by putting your finger on the exhaust pipe same when u wanna shut it off there is also a idle needle on the carb to set
