If you continue to drive you will damage your engine.
This causes pitting on the piston, head and glow plug. If you see pitting it means you are running too lean, you need to richen the mixture slightly.
Also Bro I would to be in the PI's !! some beautiful woman out there.
thanks a lot bro.. i see the picture. hope no damage was done to the engine because of these
( u see i ran a 45 min final with that mixture, my pitcrew must have not notice it was getting lean) i did not notice power loss during that final. anyway i agree with u . thanks again
