What type of compression test should I do guys ie cold hot etc? And how this wrt tuning?

Down the road I plan to lower the compression with different pistons and change the cam. But not right now…

Reading through post 34 I realized I had forgotten to mention another pitfall of locked timing is that you don’t know EXACTLY what your timing is.

All electronic ignition’s regard with rpm. If you lock out the timing and don’t account for retard the timing could be anything.

Of course, you can set total timing at max rpm but most guys just set it at idle and go.

Even if you do set total timing at max rpm you have no idea what your timing is between idle and any point that you check timing.
