Just did 5 tanks through my new Picco .28. I did'nt take any notes or anything but this is what I remember about the break in.

The first tank at factory setting cranked right up, and was more awake than any other engine I' have ever seen on the first tank, good smoke, very peppy, considering, 211 degrees average

The second tank (with no adjustment) started out like a dog... the way I thought the first tank should have felt. Lots of smoke, very fat. 140-160- degrees. No second gear.

Half way thru the third went the same. So I leaned out 2 hours on the high side and was seeing steady performance running at about 190, perfect.

What I remember of the fourth tank was 207 for the first half, easily getting to 235 the resat of the half, still running good. Especially toward the end of the tank. Pulling wheelies in fact.

Today I ran tank five, no adjusting, nice running 230-240, thru the whole tank

Half way thru tank six went the same way, running great at those temp, I slightly raised the idle, then after 3/4 still had smoke, hauling #@$, I noticed a little chirping at idle, no lean bogs or anything, so I brough it in for a temp. It read 328! WOW! Shut her off.

Are these signs of an air leak?

Half Lean Syndrome?

Or are these normal break in quarks of a Picco?

Your thought are welcome

Thanks
