Rotax 912ULS with about 60 hours. Maximum RPM at full throttle is only 2600RPM
Had this plane out about three weeks ago. OAT: 93F, CHT : 245 F, engine normal WOT RPM about 4950 to 5000.
Started up to fly today 9/29/25. Max RPM at WOT is 2620 , Fuel Flow indicated 6.7GPM, Fuel Pressure indicated 3.1PSI.
Fuel: 100LL
>Disconnected fuel lines, checked fuel flow at filter, gascolator and at engine fuel pump.
>Check carburetor throttle and choke linkage.
>Checked fuel quantity in tanks.
>Let engine cool and restarted several times, max RPM remained about 2600 RPM.
Engine starts up and runs smooth.
No abnormal sounds or vibrations.
I would greatly appreciate any advice.
