I'm the same bidderman, picked up loads from watching folk work on cars and from the advice that gets given out on forums.
Sadly Sparky seems unreceptive to people with a difference of opinion but the only advantage I can see of that is to pray he fixes his own car inline with his own incorrect advice, thus accelerating the means of his demise from this world and improving the gene pool for future generations.
I'm sorry that was harsh, I do apologise....
A little bit.
Seriously though, I would never wish death upon anyone really unless they had done something seriously sick or personal. I just hope Sparky can learn to receive advice as well as he tries to give it.
