What is the thickness of the silicone gaskets people are using? Mine seems to be about 0.8mm.
The instructions from Paul that came with the cam say "Set the cam equal over TDC. Advancing the cam gives more bottom end retard means more top end should you need to change from this setting". I am not sure exactly what that means though.
A degree wheel would be nice but I don't have one so I improvised. I put tape on the flywheel and set up a fine wire pointer on top of the crank case. I then used a DTI on the crank to measure TDC and make a mark on the tape against my pointer. I then did the same with the DTI on the inlet and exhaust valves. Nothing was done hugely accurately but I did it multiple times to make sure the results were at least vaguely consistent.
As it is currently set (with the marks on the gears matching as it happens) the point at which the inlet is just starting to open and the exhaust just finished closing are about equal around TDC. Moving the cam gear to tooth forward or backwards would make it definitely less equally spaced. I'd have to move it around 2 teeth to get the cam opening right on TDC.
Given I am limited by how much I can adjust things anyway I think this is as good as I can make it now.
