[ROVERNET - UK] P6B compression / carb adjustment - some answers

[Paul Smith]

I can remember Kent saying DO NOT use heavy oil as the oil pumps will strip gears - better to have a light grade synthetic.  I use the Shell, so far so good.

Hi Nettters

Many thanks to you all for reading and to Roland Slats and John for their
replies.

John asked some searching and relevant questions about the way the
compression test was done and the condition of the plugs, and I don't have
the answers at the moment.  My mechanic friend John did say that a number of
plugs were in poor shape, and I did not think to ask about their condition.

This morning I went to the carby shop to see the man who rebuilt my SU's. He
plugged in the exhaust gas analyser which showed a very high 9% emissions.
He then unplugged the breather pipes that go into the carby and there was a
lot of smoke.  The expert answer to my rough inconsistent idle is that the
engine is lunching on its own oil vapour and will soon be ready for a
rebuild.

I now have a heavy Penrite oil suitable for older engines, and will keep on
driving the old girl carefully while I price a rebuild.

Kind regards

Peter Mitchell
