I have come across a data sheet once published by Newnes Motor Repair and Overhauling for the late 1930s 4/4. It has details such as firing order, Solex carb jetting,valve timing, ignition timing, tappet clearances, plug gaps, toe-in of front wheels, tyre and oil pressures, recommended lubes and battery capacity.
Anyone out there need any such info??

I have a 1938 Series 1 4/4. It may be interesting to see what is being spec'd.

Cheers,

Some good stuff. Do they indicate which engine. Standard Special or Coventry Climax??

Cheers,

Sadly not. There are two columns on the sheet labelled 1939 and 1937-38 but no engine type. Details in both columns are identical! I think the Standard engine was introduced in 1939 but whether it would have same settings as CC engine is debatable?

Makes sense. I suspect CC as you surmise.

Cheers,

I saw this thread a bit late. But if someone is interested I still have some pdfs for these cars. Instruction manual, lubrication chart, repair manual.
Send me a PM if interested.
