All the direstions say is
For a correct setting of the sliding parts is required 15 minutes about of running in. In course of execution keep a low rpm zone by avoiding sudden acceleration. A previous carburettor check let obtain the optimum carburation by a minimum rotationg of base and speed needles.
I guess its translated from italian, well not very specific anyway. I know that Im going to get it up to 200F right away and run it around slowly on the first tank and increase speed every tank until around the 6th or 7th tank when Ill start leaning in small increasements constantly monituring the temp. I will probably hit some full throttle bursts by the 9th tank and take it on the easy side for the next few tanks before I tune for maximum performance. Im just not sure if I should heat cycle during this process.
