Posted this in another thread here in the engine conversions but have had a few emails saying I should start a new thread so more people would see it.
Just a small video showing how I find top dead center and time engines for 28 deg.

The top dead center methord will work with most engines but not all igntions are made to be sat at 28 deg before top dead center such as DA, 3W ZDZ and a few others, They are made to be set form 3-5 mm before top dead center.
