.....and it was a bit out!!. D reg 3.5 Efi RRC that has been down on power and pinking like hell under load. Got hold of a timing lamp and read the BoL to see how to adjust it.
Warm up engine Attach timing lamp pick up to No1 Cylinder Disconnect Vacuum advance pipe from dizzy Point light at timing points Cant see timing points, so clean them up Point light at marks and blimey thats a long way out!!
The pointer was on the 'o' of 'Before'!!. According to the book it should be TDC +/- 1 degree. Not what I had which I worked to be roughly 6 or 7 degrees before TDC!!!.
A quick rotate of the dizzy and things are how the book says they should be. It's like a new car, it pulls up hill, no pinking at all and best of all the MPG seems to be much much better. Next step will be fitting Polybushs.....must get the gas axe ready!!.
