hi camel,
never be ashamed. we all started somewhere with something, this is what this forum is all about, HELPING OTHERS, i personally have been into / had ( breaking, restoring, servicing and latterley selling new and s/h spares for them ) the p6 for 13 years and have like many others gained a lot of information and knowledge. i never profess to know it all as you still keep learning even after years working on them. the main thing is you and others are keeping them on the road and with the help of this forum find problems, solutions etc quicker and hopefully cheaper.
