burnt piston!
what causes pistons to be burnt on the only on the intake side of the pistons? a little on to top, most on the top of the first compression ring. could it be timing? fuel? or ring did not seal properly?
sorry its a non honda engine. its a toyota 4agze. made 291whp 240lb tq. emanage ultimate for tuning. fuel set up. walbro with 750cc. timing i thinks is at 20deg at full boost 18psi. ill take a picture later.
sorry. its a crappy vga camera phone. the piston is forged ceramic coated. the white parts on top and side of the piston is burnt. scorched and pitted.
