Hey Walt,
I'm sure that everyone has considered this, but worth saying anyhow,eh
.
IF the dizzy bushing/shaft clearance is moving/bad.. clearance is bound to be off..depending on how bad/much bush to shaft is..
That said, I run .025 to .026 gap in my four cylinder dizzy (with new bush), and always have, without any problem, i.e.- missing, arcing.
Of course, on my type setup, I can take cap off and make precise measurements (after putting on CVS .99c eyes).
If I couldn't see , as with crab/helmet, I'd set gap with unit off of engine by placing some matter (clay/wax/solder/whatever)on ends of rotor OR cap , spin it slowly...and keep at it until satisfied. And, yeah , I'd use .025 to .030 and be consistent at whatever gap I pick.
Note: obviously the points of contact MUST be clean to help prevent arcing.
