<DIV><FONT face=Arial size=2>Hey Jim (and others),</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What kind of problems did you notice that made you
come to the conclusion that you needed to increase the pump pressure? I had a
great running 1.45 until the rear bearing exploded and took out the engine.
Horizon was great and replaced that engine with a new 1.60. I have not run my
new 1.60, but I have about 40 flights on another one. I didn't think the power
was as good as the 1.45 I had. But, yesterday I put some Cool Power 20% Pro
pattern fuel in it (I usually run 15%) and it seemed to do great. I am using the
MC carb and did notice that I had to richen the curve quite a bit to make it
run. Anyway, I just wondered if I should adjust the pump. I did have one dead
stick that I still had about 1/3 of the fuel tank left and I am not sure why
that happened. Otherwise, the engine ran well. </FONT></DIV>

<DIV><BR></DIV><BR><FONT face=sans-serif size=2>Hi Bill,</FONT> <BR><BR><FONT
face=sans-serif size=2>Experiences like yours are not fun to go through.
In 2002 I replaced the rear bearing in a Webra 1.45R after 200 flights.
That life span is good for me. I never ran the fuel out or used
after run oil (living in high desert at the time). Matt K. is now
running the original piston/ring/liner from my first 1.45R. I started
using the Webra 160 with M/C carb 1 week before the 2004 Riverside, CA
contest. This engine has run so well for me day-in-out that I do not
feel it necessary to convert to electric (given the full spectrum of equipment
& price considerations at this time). The engine has very little
vibration and I've gotten quite used to not having to touch the engine when it
is running to adjust it. The speed envelope of the plane can be
customized to your flying style - once you learn the engine. I think
there is two pieces of advice that make a lot of sense when it comes to engine
setups: 1. Run what you can afford to replace, and 2. Run what you can
get help with in the local area with other flyers. In Lancaster, I had
Jerry & Tony to help with my first Webra 160 setup. Within 1/2 a
tank from first flip I was flying the plane. I've found that you need to
increase the pump pressure by 1-2 turns.</FONT> <BR><BR><FONT face=sans-serif

thread....</FONT></TR></TBODY></TABLE><BR><BR><BR><FONT face=Arial
size=2>All:</FONT> <BR><FONT face=Arial size=2>I have been "lurking" on this
thread, and feel compelled to contribute - our list is a tremendous source of
information, and in this case, "trends"..</FONT> <BR><FONT
face="Times New Roman" size=3> </FONT> <BR><FONT face=Arial size=2>-
when I returned to flying after a six year layoff, the two stroke
motor was very attractive to me. I really like "plug and play"..... the
simplicity was simply overwhelming in my choice, even though the YS motors I
used to run were, in looking back, "plug and play"...</FONT> <BR><FONT
face=Arial size=2>- I purchased the Focus ARF to quickly get in
the air, and of course was exposed to the Webra option through the Piedmont
setup by Lee Davis</FONT> <BR><FONT face=Arial size=2>-following nothing but
problems with the Webra motors (two of them) I have come to the following
conclusions:</FONT> <BR><FONT face="Times New Roman" size=3> </FONT>
<BR><FONT face=Arial size=2>1. The Webra motor, when it is setup
and working, is fine. Problem is, for me it won't be for very long.
That's a real bother for those that burn much fuel. A
pattern motor should get hundreds, not dozens, of successful flights before
needing major work.....you know, having a prop spinning through completion of
landing. I use PowerMaster 15/16, OS F plugs, APC 17x12...typical
setup!</FONT> <BR><FONT face=Arial size=2>2. Webra needs to deal
with the pump and rear bearings... the rear bearings seem to be the source of
most all of my problems... when they start to go, particles of metal start
ruining plugs and scratching the cylinder wall. I have replaced one
pump, and two bearings so far in two motors. They are running fine for
now, but again, I know that the bearings will soon be going south.</FONT>
<BR><FONT face=Arial size=2>3. Horizon is wonderful in support of
the motor, but until Webra or an aftermarket company comes up with a
sealed/stainless rear bearing, Horizon is swinging a "leaded bat". The
rear bearings and their very limited life span make it difficult in a typical
pattern application....i.e. burning lots of fuel. </FONT> <BR><FONT
face=Arial size=2>4. The pump seems to work fine as long as the rear
bearings are good.... at least for me, the rear bearings have caused my
problems..... the pump I replaced was done by Horizon because in frustration,
I totally took the pump apart, looking for anything. Didn't find
anything, but managed to destroy the pump. I know why we aren't supposed
to completely disassemble the pump - Horizon wants to send them back to Webra
for evaluation, and when they are not just taken off the back of the
motor, that's not possible. If you suspect the pump, send it to
Horizon. My experience with the pump is pretty simple..... if you can
make the motor rich, the pump is working just fine. When it's working,
all the mixture stuff is very easy to set....... and, I don't run the mixture
control carb on either motor...</FONT> <BR><FONT face=Arial size=2>5.
I run the motor dry after use, and have used, and have not used after
run oil. If you fly a few times each week, I think our motors should do
fine by just being run dry.....sure, oil 'em up for storage, but not to fly
tomorrow! </FONT> <BR><FONT face=Arial size=2>6. I agree
with those that suggest we shouldn't bang on a company.........some guys claim
to have had no problems! Trouble is, lots of people have..... As the
owner of two motors, headers, and pipes for these, I'm in no hurry to trash
them! Quite the contrary, I am anxious for there to be a solution!
</FONT> <BR><FONT face=Arial size=2>Did I mention the rear bearings??
Seriously, that's the biggy for me. As soon as I get the header I
ordered from Karl Mueller, I will be flying with a new OS 1.40, EFI bearing
set already installed. The Webras will go in a drawer, pending bearing
updates. Based upon my experience and what I've seen as I've lurked on
this thread, I'm going to call this whole thing with the Webras a
trend.</FONT> <BR><FONT face="Times New Roman" size=3> </FONT> <BR><FONT
