Honestly, chaps i didn`t know any of this and it certainly makes some good reading.
Glad that it`s been asked and answered.
I`ve not had as yet to time up my G40 engine but i`ve made notes of this post for when i do.
Every day i read some more of my Haynes Manual to familiarize me with issues i will encounter
when converting my car.
Tho know doubt its not all correct but then i`ve got you chaps behind me
Regards, Fred.
