This is our second break-in run of the day of the UL Power UL520iS engine with the newly installed Culver 64" x 76" white maple custom propeller. ([ Ссылка ]). This is a hot start, where the engine oil is already up to operating temperature, and the cylinder heads have had time to cool down to about 100 degrees F. The engine is fully heat soaked from the previous run. As you can see, there is no problem at all with "vapor lock" with this multi-port fuel injected engine.You can learn more about this engine at [ Ссылка ]. (I have no business affiliation with UL Power.)
