TR6 follow up I realize its been said you should do a full throttle run then shut the engine down, which i have not been doing, however here is a picture of #6 for comparison (second from the back)of a new TR6. I dont yet see any speckling on the TR6 (colder) insulator at all, and a nice dark top ring. So i dont think there are signs of being lean or detonation. Looks like a win so far.
The timing on the ground strap is a bit past the curve so might be too much, but at this point i would think that would be a tuning for power.
What do you guys think of this one?

It definitely looks like the TR6's are an improvement. However NGK plugs have a cadmium coating on them that makes reading the timing mark difficult. Use some fine sandpaper and sand the outsides of the ground straps until they are a smooth even color. This will make reading the timing mark much more accurate.

Oh but he is intentionally trying to burn the engine up. Otherwise it would have a wideband literally the first thing you buy when attempting to tune/learn about tuning is a wideband. But everyone would rather see him melt the engine! 'they' talked him out of it! Im done!

As suggested in this thread, you need a wideband to tune AFR’s. Once wideband reads satisfactory, then fine tune with spark plugs. Plugs don’t lie, ever, but wideband will get it very close.
