The tough part these days is finding carburetors and mechanical fuel pumps that will last with this ethanol-blended fuel. IIRC, there are carbs rated for the E85 blend, you can just re-jet them as needed. Mechanical pumps are the bigger problem, though electric pumps can be had that are more ethanol-friendly.
I can pick up a couple of spare mechanicals, or wire in an electric without too much difficulty.
