Vespa gas has been sit5ing a year
My Vespa has been sitting a year and has old gas and oil. I have 5o get a new battery to get it running. As for the old gas, is there an additive I can put in then fill with new gas?

All you need to add to fuel to refresh it is fresh fuel. Just add a litre of fresh fuel and the old stuff will perk back up again. Unless it has water in it, then you will need to flush it out.
I too have a vespa that sat for many years, I removed the carb and drained the gas, replaced the fuel tap, cleaned the carb and jets reassembled and still have an issue when I accelerate. The scooter stars first try but bogs out on acceleration.
Did you change out your filter? Also did you make sure you tuned it correctly. If it is a two stroke, did you take off the exhaust manifold and clean all the carbon out? As this tends to sludge it up.
