STOP!
Just read WORKS UNTIL screw onto Battery.
Do NOT Grind on things you are not certain of.
If the
tank is Open when off the Battery, as in you can draw through it comfortably. ASK WHY
Now, Look at the Base of the ce5. The part that actually screws into the battery.
Is the center pin on the BASE sticking out excessively?
Is The ce5 Difficult to start threading onto the battery?
Do you have to put downward force to screw the ce5 down?
Did You place both heads side by side to compare TOTAL HEIGHT?
With the Heads 2 things are critical.
1) correct Height
2) Correct center pin for - power contact
a) Pin to tall Head will not screw on flush or will push center contact down battery tube
b) Ping to short - No contact and no power to coil

vjdossy it seems you have thoroughly hijacked k9qlq's thread.
Hopefully we can figure this out in a way that will also assist the original Poster.
