Hello Everyone.

Had an issue arise with my sonerai today.

If i throttle up too quickly the engine will hiccup for a second and then keep running fine. Seems like it may be starved of fuel for just a second. i'm hoping it's just a fuel filter which i'm going to change tomorrow but has anyone had a similar issue.
I had the thought that it might be running to lean. There's no mixture adjustment in the cockpit.

Thank you.
