I am needing some help getting my Royal 46 to run properly. The engine is fully broken in, and has great idle and top-end. The problem I am having is that it does not want to go from idle to full-throttle without hesitating alot. When the throttle is hit from idle to full, it dies out then starts picking up till its at full power. Anyone know how to help clear up its transition, Thanks!

It probably smokes a bit when you firewall it, no? Sounds like the idle is about an 8th turn too rich.

What's the orientation of the engine, upright_side_inverted?
Where is the tank centerline in relation to the venturi?
What fuel, prop and plug are you using?
How as it broken in ?
Let's start there

I got one that runs as good as my TT .46, excellent idle, excellent transition, and good top end-slightly less power, but great for sport flying.

The engine is mounted upright, I am using a for idle bar plug, long I think. The engine is well broken in with about a gallon of 10% through it if not more. I am using a MVVS carb. it picked up a few hundred RPM with this but I dont belive it is causing the problem. The tank is just about lined up with the carb. I am using an 11+5 APC prop. I am about to put this plane on a fun-fly and need the good transition out of it
