I seem to have a problem with spacing on my e50 motor when i installed a 70cc kit. as soon as i tighten the nuts to the head, the engine wont turn over. I have a paper base gasket and a .2mm head gasket.are the treats kits just cut differently and require different gaskets to put on? has anyone encountered this problem and had to use a .4mm gasket? this is the first time i had spacing issues with my motor before
