This isn't for my Barracuda, but my boss's motor:
If you think you're getting too much gas in the cylinder, it's not burning it all, what would be the first thing you look at/tinker with?
He took it in this weekend to a guy who said he needs a hotter spark. I suggested leaning his fuel/air mixture, reducing his jet size, or maybe adjusting his timing. But I'm curious what you suggest. Thanks.
