XRAY - Model racing cars

Would like to check with u guys that how the engine performance, tuning n any oil leaking problem? I am interested to get one but worry about the engine! The engine looks very much like the NB16 buggy engine and that engine giave me lot of leaking n tuning

Same Toki engine used in the NB16. I was lucky enough that the engine didnt leak just alot of tuning. Plus w/o plastic ex. manifold and muffler.
Use the correct fuel the engine specs. Te engine likes to run lean. My engine lasted me 7 gallons of fuel. Still was running till I change to the Picco-Zero. Just a suggestion. Purchase the model w/o the engine, and purcase the Picco. or , purchase the picco and install it in the NB16.

well I have run both of my toki engines and one is leaking and the other one is not. so far I have run around 20L thrug the first engine (the leaking one) my engines are punished to the maximum limit because I run at a scaled 1/18 asphalt track, so the engine don´t get so good cooling. but it seames to me like the engine actualy like being punished a littel. I adjust it a littel more buggy style because of the layout of the track. the tuning of this engine are actualy pretty easy once adjusted it´s just the normal lean/fat adjustment needed.
