New Mintors

[Henderson,Eric]

Lance,
       I much prefer to have a tight engine. (Most engines that we receive are a compromise so that the users don't break them). I would suggest that the break-in instructions need to be a bit more comprehensive. The 170 may also be different to the 1.40. (The Moki needed a similar break-in.) BTW it was not cowled in very much. I had removed the top to accommodate the DZ pump. I then removed most of the front to accommodate the carb. (The Hydeout is quite narrow at the spinner.)

I tried using two different plugs on my modified OS 1.60 and one always died. I will switch to the recommenced A5's when I get a cool run and see how they do.

The vertical was strong even though it was just a 16" prop. It was also nice and quiet. Looking forward to trying some of my 3-blade props later on.

Eric.

Eric,
I ran a gallon thru my two on the bench before putting them in the air.  There 
have been several posts of people putting them up quickly and they've reported 
success.  More power to them.  I'm sure there are different break-in 
procedures that work.
  In my case, similar to yours, the engines seemed tight at first.  I found 
that they ran fine at mid throttle out of the box and the range extended with 
a little running.  Your procedure sounds like it's working, but I agree it may 
not be for everyone.
  The way I've always looked at it, break-in is a temporary condition.  No 
need to rush it.  I have a friend with a Saito 180 which took a while to break 
in but then became a very reliable engine.  I'm not trying to associate one 
engine with another, just pointing out that reliable engines result from a 
variety of starting points. 
  Thanks for sharing your experiences.
