don’t bother pulling the P/Valve assembly apart this time as i would say you will be recoating next time, just get a can of WD and spray in the p/v area and leave then blow out with copious amounts of air until you are satisfied it has got rid of all loose type crud.
now go round the barrel with some scrotchbrite by hand and kero.. lightly
Ok next you need to tells us what jetting you are running, what oil and ratio and where you spend most of the time in throttle position, cause that piston and cylinder wall is telling me a story……
