racin69z Posted February 3, 2025 Report Posted February 3, 2025 I have a mild 358 build with stock carbs that I am tuning on. I think I'm fairly close on jetting but wanted some more experienced opinions. I feel like my jets are smaller than most with similar builds. I am at 270 right now, and it still feels a little fat up top by seat of the pants. Started at 290 and it wouldn't rev out good at all. I got it warm, ran it up the road, changed to new plugs, run 1-6 held 6 for a few seconds pulled the clutch and shut it off pulled plugs and drove back on old plugs. Each ring has a light and dark side. Moreso in the left plug. Left plug is the first two pics Quote
Jereme6655 Posted February 4, 2025 Report Posted February 4, 2025 The first plug looks a little light to me…. But I also would rather run a touch fat rather than rebuild because of a lean burn down. Just my 2cents. Quote
locogato11283 Posted February 5, 2025 Report Posted February 5, 2025 I've never done a plug chop. What color were the straps? Quote
racin69z Posted February 7, 2025 Author Report Posted February 7, 2025 They are greyish with color change at the 90 degree bend. Quote

locogato11283 Posted March 23, 2025 Report Posted March 23, 2025 They are greyish with color change at the 90 degree bend. Sounds lean. They should be cardboard colored. Quote
