Mike,
I'm glad you're retired mate.
Forgive me for not being an expert in every regard to my vehicle, but I believe that's why you got to have a job - because everyone cant know everything - frequently that is the purpose of questions.
I'm glad I only saw this after another person attempted to be reasonable in providing an answer, and long after the problem was solved.
You are most certainly entitled to your opinion, however that's there is something to be said for the sanctity of ones own mind, so do feel free to keep entirely useless commentary out of informational forums as you provide nothing of value to those in them.
In short - I recon you're a bit of a ****.
But hey - keep posting your stats. I'm sure somebody cares.
Best, Tracy
