That is correct. I was hoping someone would have a fix or an atomizer recommendation
Which version of the Magneto do you have? The V1 without the adjustable pin (i assume) or the v2 with the adjustable pin?
The best solution if its a v1 is to grab a v2 topcap for around ~$10 that has the adjustable pin, that should solve the problem.
Otherwise you could try extending the contact pin on the nimbus by setting the atty/510 connector in something hollow and round (like a beauty ring) then apply gentle but consistent pressure to the center shaft(on with the insulator around it) in the atty and it should push more pin out on the bottom. Move it a bit test etc until it fires, but beware its gonna change the way the atty sits on the KTS.
