Hello,

I bought a RC car 7 years ago, but haven't driven for 5 years. It's a buggy 4WD with an 3.5cc, I guess. I'm a totally beginner. Can anyone tell me what kind of engine this is and how can I easily adjust it? I saw some screws to adjust at the other side of the engine. I started it yesterday without any problem, but when I accelerate it goes down in rpm and stops running. Sometimes when full gaz and I do back to neutral, he stays full gaz for 5 seconds.
Anyone some help?

Tnx,
Jan (Belgium)
