Ivy: New Piston and Rings

Process of elimination to determine why Ivy's still smoking.  Figured first easy fix was just to swap in a new piston with new rings.

Had a new STD piston marked "HF" and installed a new 5-piece ring set.  Three-piece oil ring went on easy.  Top two rings were a bit more fiddly.  Used the ring pliers but was very careful to only open them the bare minimum so as not to snap them.

Install went smoothly, somewhat in part to all the practice I'd put into getting the piston circlip in and out.  Top Tip is to use the small punch to get in under the circlip and then coax it off.

On first start, no smoke!  Good sign.

Took her out for a ride and was all going swimingly at first.  Did a big lap around the hood.  Stopped at the top of the street to check smoke and she died!

Took her into the garage and after a few checks realized she had no spark at all!

Tried swapping the plug but no dice.
