Now, Since this is my first 4 stroke, I ask you to be patient.
The TT engine manual is not very clear to me, I downloaded the OS 91 FS manual and things are a bit different: full throttle for 5 seconds at max rpm, then slow down by opening the needle valve. Seems that the Os breaks-in with a 10 seconds alternate process of closing and opening the needle valve at full throttle! . In the TT manual no mention is done about throttle setting, it just says to not exceed 5000 rpm in the first five minutes… does it mean I have to run at full throttle for the first 5 minutes checking not to exceed 5000 rpm? Or should I throttle up and down for the first tank of fuel not exceeding 5000 rpm… uhm.. Please help me understand the correct procedure.

Thank you
david
