That is so good to hear!
I was just out and started the magnum 46 for the first time, ran 2 tanks. It is a great engine and the fuel seems to be perfect!
The lowest idle ever.
If you do not have it, the Magnum 46 manual can be downloaded from

Fuel recommendation is on page 3. They actually recommend 10% nitro for break-in and 10 or 15% after that. Even though it is not their recommended break-in fuel, the fuel you have should be fine. Byron’s is a quality product. Just avoid running the engine really lean to avoid overheating.
In the US, nitro is ‘relatively cheap’ so we tend to run a lot of it. The fuel companies are smart. They promote nitro as the best way to make our engines reliable and easy to tune. The more nitro we run, the richer we have to set the needles. That means we burn more fuel and give them more money.
