So I have to relate a quick story. I was having issues with the performance (blue) CDI I've had for years, once I put on a 58.5 BBK on my 150. Hard starting, kickback when kick starting, etc. I went thru the threads here and found Alley talking about the CDI that John sells that actually advances the timing with RPM. Ordered it, got it in a couple of days.
But I had a hell of a time trying to get it working. Finally decided to call NYC directly even though it was after normal business hours. I was surprised to have John answer the phone directly!
After getting over my surprise at a real person answering the phone I described my issue and then John started suggesting things to test. We spent at least a half hour on the phone, with me and my trusty multimeter testing everything we could think of.
We did finally determine that the CDI he sent was faulty and, while we were on the phone, he grabbed a new one, slapped it in a box and printed a shipping label. I got it a couple of days later and WOW, what a difference. No more kickback and as good or better performance as the blue one!
I can't say enough about the personal service and integrity he showed. Thanks again tvnacman !
