This site has some nice photo's of a B&S carb; this will be a similar format to be used for this section. Diagrams of the three or four different Carbs used on the B-Series will be put here for references.
Writer Note: I am currently restoring four gas tanks for a few machines. So I am going to be running some experiments and doing all at once. I probably have more gas tanks, but can't sell them until I fix what I have for what I need them for. Note, gas tanks sell fast and get good money. They are a high percentage of what a used tractor is worth!
This is a draft of the sections:
1. Prepare tank for flushing 2. Clean the tank 3. Acid wash the tank 4. Removed the sludge 5. Sealing the Tank 6. Replace the hoses & fuel filter 7. Reinstall the tank 8. Summary Gotcha's
