It should work fine. A bit unusual but nothing to worry about as it works. The only real issue was you couldn't put your finger over the intake to choke the engine. But you can block off the exhaust outlet on the muffler instead to choke it. If I remember it didn't do well, at the time it was made, due to most people weren't using mufflers yet. Thus choking the engine to start it was a problem with no muffler. But it also was a aftermarket item and people had a tendency to not want to get one even if it was better.
