Type 65 static timing
#13
Hi   Colin
 
You obviously have a clear grasp and should find experiments interesting. Manual advance (including fitted as override) gives you something to do whilst waiting for acceleration, grinding up hills etc.
I am surprised that the manual range is less than the stock 1934 car but much depends on the lie of the levers. Can be arrange to be very non linear.
A light spring from the distributor is useful to take out back lash.
 
My comments applied more to Sevens generally, as did many of the other responses.
Any 65 today may or may not be all dinkum; the engine likely close to other common modified Seven engines.
 
Whilst on the topic, very retarded cars are reluctant to rev through gears and seem to gain rpm in surges. Contrary to what may logically expect, the exhaust  with retarded spark sounds flat. In their day many Sevens had very worn mains and were run and sold very retarded.  The car you eventually got was often very different from the smooth but lifeless one road tested!
 
For car engines generally I have never clearly established the relation between octane and spark advance. Some sources state little relation, others recommend a wide range. (ie Ford V8 40 octane 12 deg retard, 80 octane 12 deg advance)
 
If new to Sevens attention to the safety aspects, esp steering arms very worthwhile.
