hi
i would like some information if poss ,first of all i have a 26cc cy engine which had been fitted with a 2mm stuffed crank and a 28.5cc head ,i was told this was done to make it a 30.5 cc ,but when i got the engine it was part of job lot, the head was cracked at the bolt hole ,so i thought i would strip it to see what had happened , i have just taken the head off and noticed that the gasket is a paper one ,i thought that it should have been copper and two of them to gain the 2mm back ,i am thinking this is why the head has cracked ??
what do you guys think................Phil
