Technical data for 1937 - 1939 Morgan 4/4 - 29/12/17 03:54 PM

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.

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.
