Thermoquad on 340 (plug photos)

You added more fuel but not running rich? You must be burning all the fuel then.
Glad to hear the TQ is working out for you.

Yes, thought I was adding a lot with the .149 secondaries on top of the .101 primaries, and that the .038 nozzles would be too much for sure, but it just took it all with absolutely no sign of being too rich so far. I have done a number of drives and WOT runs, and it's just now looking good. :thumbsup:
