Hi everyone

As I am new to Rc cars , ı recently owned a Xrc 1 GP car but there seems to be a problem. the motor runs but there is a leakage of grease like oil under the exhaust. I learnt that the previous owner of the car, who drove it only for two times, used a very high oiled gas so i thought that this grease-like substance can be raw fuel which the motor failed to burn

Moreover blue smoke comes from the exhaust. I immediately will replace the oil-gas mixture tomorrow.

Any help about this issue will be appreciated. Thanks
 
Hello and welcome to the forum.
What kind of exhaust do you have on there? Is it the stock can or a tuned pipe? Are the stingers coming out the bottom or the side?
I don't think it is raw fuel as much as too much oil. It should be ok to change the fuel since he only ran it twice. The engine is probably ok.. Just make sure you use a 25:1 ratio for the fuel to oil mix.

You will always get fuel residue thats just the oil mix in the fuel,use a 25/1 mix that should reduce the gumming effect.Blue smoke is burning oil the will always be a bit of that.

thank you very much for the helpful replies

as far as ı know the pie is stock pipe. ı think the manifold bolts are not tight enough and in xrc the manifold is under the motor so the famous substance ( grease like sth..) :D:D is filled to the manifold i will plug the motor out and celan it then use my 25:1 ratio 95 octane fuel and fully synthetic castrol 2 stroke oil

Moreover can anyone send me xrc 1 manual in pdf. ı don't have one and i need to adjust high and low but i don't know optimal settings

lastly (believe me this is last question) :D throttle servo seems to be powerless it is futaba 3003 what do you think. should ı replace it
