What sucks is you could put modern catalytic converts and a modern carburetor, have way cleaner emissions than when new and fail because its not the 42 year old worn out stock stuff it came with unless its CARB approved, which is a costly process.
Today's fuel is not crap, its designed for evaporative emissions and fuel injection. It lights off in a heartbeat which sucks for a carburetor as it's meant to be in a contained system not subjected to atmosphere.
