The '36 Ruby (C/R of 6:1) is quoted as 3/4" BTDC at the flywheel, which I reckon to be 8 degrees, so I am inclined to start there in the absence of better info.
I am new to Sevens and to manual timing on the steering wheel. I imagine my best course may well be trial and error, but I'd quite like to know where I should be starting from!
Hi Colin,
As you will be aware the timing marks on the Type 65 are a nightmare to get to.
I have always used top dead centre on Number one cylinder then rotated the distributer till the points just open.
This will usually get the engine to start, once started I will adjust for the fastest tick over with the hand control in the mid postion.
I find that I do not gain much by advancing to much while driving. If you over advance the engine will sound harsh.
Do not rev the engine off load too much.
