[NSRCA-discussion] I give up -- almost new Webra 160AAR aerowith MC carb for sale

[John Pavlick]

David,
 Yeah a lot of guys up here in D1 run either the OS 140 or the 160Fx. Both
are good runners. My 160Fx ran great all of last season except for one
contest where I had some bad fuel. The 160 is a real good low cost motor for
pattern. It makes good power and it's real easy to tune. It's not sensitive
to pipe length, but you need to add a pump and that requires some tuning.
Not hard to do and once everything is set up it will run the same no matter
what. VERY reliable. The 140 is a bit more sensitive - more radical timing
etc. It is still very reliable and relatively easy to tune however. It won't
give you any headaches if you know how to set a needle and measure a pipe.
The bearings are the only weak point of these 2 engines, but if you get some
from Boca and put them in when the engine is new, you won't have any worries
for a long time. I used 2 stainless steel sealed bearings - front and rear.
My thinking was to keep the fuel completely out of the bearings. So far it's
been working and I know a few other people who have done this with similar
results. Some guys only change the rear bearing and while this is probably
all you need to do, I figured my idea was worth a try. Good luck with your
new setup. I'm sure you'll be happy.

  John,

  Thanks for the note.  I did not talk to Dave Lockhart, but you are the
second one to give me that advice, so I should have.  There is no going back
now.  As intrigued and impressed as I am with the Webra, I can tell it is
not for me.  I need something that I can get going in a day, and not fuss
with it for a whole season.  From what I hear the OS is that engine.

  Update on the Webra that I am selling -- I just removed it from the plane,
took the header off, and peaked through the exhaust outlet.  Piston looks
real clean as if it has never been run.  Rest of the engine looks the same.
I put some after run in the crank.

  David
