Remember this?
Well, after many hours of cruising (and scraping) I decided it was time for a tune and an electric fan to help the old girl into the 30+ mpg club.
Out with the old fixed original fan…
and in with the new… I’m not the most savvy when it comes to wiring and electrics, so wiring in a fan and it actually working was a result!
With that done it was tune-up time; old-skool style!
Gas tester plugged in the back
Color tune up front
If you’ve not seen one before, it’s a spark plug with a viewing window in it so you can see the colour of the combustion: White-ish = lean, Rich Blue = Stoich, Rich = Orange. This is retro tuning at its best!
Here’s a pic of it running looking down the viewing tube:
Runs much better now! Should be less juicy too.
