Underage Pilot,

We haven't heard from you, did you get it sorted out?

Some things covered that are important: Use at least 15% nitro, peak the engine but not over lean (you need the RPM because this is a heavy plane.

One thing not mentioned, is this a new PT-19 or an older one? They originally came with a Babe Bee installed, then product engines became the choice. Early product engines have one intake bypass, as did the Babe Bee. These do not have the power of the modern two bypass (Sure Start) product engines. (An intake bypass is the slot(s) that moves fuel and air from the bottom of the engine into the cylinder.)

Between hand flipping and the spring starter, you should not need a starter. I never use a starter on an .049 engine.

By the way, your engine will be easier to start once it has some run time on it.

Keep us posted.

George
