Surely he's set the strobe to 12 degrees and then set the dissy at 12 degrees (ish) on the pulley so we now have a total of 24 degrees advance... if the strobe is at 12 degrees then we should be aiming for the marks to be at TDC (as the strobes clever electronics have delayed the strobe 'pulse' by 12 degress)... if the stobe is at zero then aiming for the 12 degrees marker...???
Thought I'd have a look at what else you were putting on YT after the discussion in your Stag video about the timing being180 degrees out. Promise I'm not stalking you now, I'm just trying to be helpful. You might want to check the manual for that timing light as that is not 'usually' how they work. Dial advance timing lights are useful for if the car doesn't have the decent timing scale adjacent to the crank pulley that the Stag has. If all you had was a very basic timing light you would indeed want it to flash at 12 or14 degrees BTDC on the Stag depending on the build number and is easy to read that value on the Stag's scale with a basic light. However if your car didn't have that scale it would be tricky without sticking timing tapes to the block which is where a dial advance timing light come in handy. The idea is you set the timing light's dial to zero and run the engine as normal, aim the light at the timing marks and turn the dial till the timing mark on the pulley lines up with the 0 degrees pointer on the block, whatever is then on the dial is the advance value. With 12 degrees on the Stag's scale and 12 degrees on the timing light means, I think you'll find, your timing is 24 degrees BTDC.
Totally correct from another ex garage mechanic did stags , 12 to 14 degrees number 2 pot , rotor arm pointing to about coil mount bolt ( for adjustment. ) infact most maintenance things easy even the elusive stater top bolt easy with an extension over the top , your stag runs a treat , a winner id say , and thanks for some maintenance tips for stag !
You forgot to disconnect the vacumn pipe from distributor.You are setting it wrong with that still on also you are using the gun gauge wrong, sorry not picking but lets have it right.
Ex BL & Triumph Main Dealer Workshop manager here, Watched your old video, You DO set the timing on number two cylinder, you are correct there. HOWEVER, what SO MANY are missing here is it needs to be on the firing (or compression) stroke. What does that mean? Well a 4 stroke engine fires every OTHER revolution. The first ( compression) revolution(or stroke) is when the engine fires. The second is when it exhausts. Common place even in the day for an engine to be 180 out because mechanics did not understand this. Does it matter? No not really, you merely adjust the firing order to suit. I struggled to get our main dealer mechanics to understand this even back in the day, For clarity, if you can rebuild a Stag engine to run this sweetly you aint no numpty. 180 degrees out or not! That is why the Stag ran so well 180 degrees out. Hope that helps, Great channel, and I've met you and seen this well sorted yet oh so usable Stag in the flesh. This is how you want them really nice car, usable , but so concourse you dare not drive them!
Absoloutly right. Common on many engines to be timed 180 out. Engines with 2D distributer drives were a favourite for this after a rebuild! Engine needs to be at TDC on its compression stroke.

Spot-on Matey. The Stag sounds great. All the best Bob
Wouldn;t say it sounds great though.
Thanks for the demo, have you thought about mounting the coil on the fire wall to improve efficiency?
