I have a question. I have just taken my exhaust off and their is no carbon bulid up, But the other 3 exhaust ports have it. The valves a white not black and it seems to be damp in the port
maybe petrol. I have checked for spark and i have got, I have also checked there is fuel getting into the carbies and into the air flow through the verturi buy the fuel nozzel. So am am maybe thing it might be a combustion problem but i not to sure. So does anyone know what i might have a problem with. I have done a basic course in Mechanics at midland tafe so i do have some basic knowledge in the area
.
I do Have the owners manual.
