Cheers Peter for your advice, I have tried all that you mentioned & some more, to date I have tried toyota celica pistons ( same bore different gudegeon & pin height) plenty of work on the lathe but they work, the main issue I have is they melt down, dont know if it is running lean that causes it, some other P Models in the club dont seem to have the same problem, but all built the same, if you have any ideas or possible explanation please advise.
