Lose power full throttle

[Joseph Mariott]

50hp 87' Force not getting up on plane appears throttle plate not working right. Has been fine, just doing this lately. Notice plate stays at full open (plate horizontal) when throttle from speed just before fast enough for plane. Have to pull throttle back to keep from dying down.
