Hi folks. I am rebuilding a set of Zenith 40 TIN carbs. I'm trying to confirm that the existing jets are correct. Looking at the factory manual, it appears that stock for a 1970-71 US with enrichment would be:
- Main Jet: 115
- Air correction jet: 195
- Idle fuel jet: 47.5
I believe the jet on the far left is the main. I can't find any markings on it. Is that normal?
The other two at least have marketings that appear to be correct. At what point do I just ditch them due to uncertainty?
