Ok so typical newb here...I'm confused about break-in. I've heard don't rev high, don't roll down hill fast, constantly vary speed and I'm nervous to make any mistakes. This is slightly unpleasant but I'll get through it. Also, four tanks of gas? That's like 300 miles. I've been on my first tank for several days now and I'm not even three quarters through it. Today I opened the throttle a bit more than I have yet and discovered there is some power in that engine. Hmm, now I wonder if I'm not running it at too low rpm most of the time. So confused. I really don't want to destroy this engine. I have looked through the threads, but perhaps not enough. I will do some more searching tonight.
