MG MG Y Type - IGNITION TIMING
|I am puzzling on how to set the 7 deg advance advised these days, its impossible to fit a timing disc in the murky depths so I came up with this idea.|
The diameter of the engine pulley is 3.75" or 3750 tho times Pi gives a circumference of 11782.5 tho divided by 360 deg gives 32.7 tho/deg
So measure back from the TDC pulley mark 32.7 by 7 gives me about 230 tho or just over 7/32" or just under 6 mm give or take bob weight chatter.
Any comments before I blow a hole in the piston crowns?
|Bryan, I set my TF and TC by eye, about 1/4 inch before TDC is close enough for me. That's the static timing, I then check with a strobe.|

|After having my distributor re-graphed for modern fuel, the recommendation was 10 deg BTDC static.|
My calcs were 16.5mm on the pulley rim for 10 degrees.

|DON = I think my YA represents the work of 'Albert Schnittka'|
|You've got me on that one Bryan.....hang on...do you mean Albert SchnittkE??|
Actually I've never heard of him, maybe find a better composer for your YA.
Then again he might be your favourite!

|You are right my error DON I'm particularly taken by his work 'Tango in a Madhouse' I sometimes hum it to myself while working on the YA. Bryan|
