Just build a welding robot that can reach down through the plug well to get the top few threads. It'll be a fun father/son project.
With something like a WP-25 straight torch (which I don't have) I cold probably get in there....really hard to see and the rod tends to overheat and melt off dropping in the puddle. I'm leaning toward bottom taping a hole that stops 3-4mm from the chamber and putting in a helicoil. Stock there are about 2mm of threads cleared and just a little more gains space between the seat ODs as well as ensuring the coil is trapped and could really could never end up in the chamber.
As I ponder the idea that the engine may run again there are a lot of little things to take care o, one of which is an ignition timing question that has been in my mind. Dynomation says it doesn't need much timing, like 24 degrees and while that seemed quite low that is what I put into the ECU. A stock QV is like 32 iirc and Wade just send me the TR timing which is...32. I'm a bit higher compression and a bit higher cylinder pressure but 30 feels like the right place to start. The only way to know for sure is the dyno but I'm pretty sure 30 is way closer to right than 24 so I'll make that change and honestly try to remember what else I wanted to fix in the ECU to get ready to run....maybe shot for Jan2, which is the 3rd anniversary of the first run.... and fire
This graph is state of the art 1980s 8 bit processor and emissions weirdness....other than step 9, that confuses me as its clearly more than 8. The QV map only had 8 which is much easier for an 8 bit processor.
