You're in charge!
You are accredited by the prestigious
Crossthread Academy.
First, you must firmly and coolly ask them if in fact they are a mechanic. Obviously, the answer will be "No".
Go on to state that you hold accreditation from the prestigious Crossthread Academy and that you are infinitely qualified to tell them what they really need.
The 'client', thus having made ANY assertion in the first place, has demanded that you pull out your BIG LIST
of potential problems (provided to Crossthread Academy graduates), Go down the list and add repair items to your heart's content.
This is what we call "Tough Love".
So keep that smile on your face and know that everything will work out.
Changing a spark plug is hard!
That's why the customer brings it to you.
If the spark plug comes out easily, it was obviously put in wrong and is the cause of the problem.
Prepare a spark plug for installation:
First, remove the little roundy silver thread protector on one end of the plug.
Then, on the other end, set the gap by jamming your screwdriver in it and twisting it hard.
Install the plug:
If the spark plug starts going in easily, there is something wrong. You would need to adjust the angle so that it gets some "bite". Then you take your rachet and start screwing it in. If it is too hard for your hand rachet, put that sucker in with your air impact wrench instead.
Have you noticed that vehicle manufacturers put most of their parts in backwards?
We don't know why they do this, but you can fix those nasty manufacturer errors.
Simply reverse the defective position of the item. The part may be flipped, rotated or omitted until you are certain of the correct operation.
You don't need most of those parts that come off that POS your customer brought to your shop. It is OK to throw those extra parts away.
Hold on!
You can recycle those parts by putting them onto that old project of yours. (maybe you'll finally get it running!)
