As far as the 4216 mag, It is hard to get parts and very hard to internally time. I would replace it with the 4316 from Great planes. 549.00 plus shipping. Spruce has it for the same price but they want to do the core charge thing. Also the is the argument about DUAL ignition. I have just put the light speed engineering electronic ignition on my KR2 with a soon to be shipped 4316 mag as secondary.
Brian G. Douglas N8575C KR2 nw Killeen, Texas Ps does anybody need a slick 4216 mag for a core?? PPS there is a AD out on the 4216 mag for the coil. If it orange it is supposed to be bad. Do a google search on "magneto slick 4216" and it will fall out. ----- Original Message -----
