| Subject: | A List Contribution - It's Your Personal Squelch Button... |
There is an automatic "squelch button" of sorts for the Fund Raiser messages.
Here's how it works... As soon as a List member makes a Contribution through
the Matronics Fund Raiser web site, their email address is automatically added
to this year's Contributor List and they instantly cease to receive further Fund
Raiser messages for the rest of the month! Its just that simple! :-)
I really do appreciate each and every one of your individual Contributions to support
the Lists. It is your support that enables me to upgrade the hardware
and software that are required to run a List Site such as this one. It also goes
to pay for the commercial-grade Internet connection and to pay the huge electric
bill to keep the computer gear running and the air conditioner powered
on. I run all of the Matronics Email List and Forums sites here locally which
allows me to control and monitor every aspect of the system for the utmost in
reliably and performance. Your personal Contribution matters because, when combined
with other Listers such as yourself, it pays the bills to keep this site
up and running. I accept exactly ZERO advertising dollars for the Matronics
Lists sites. I can't stand the pop-up ads and all other commercials that are
so prevalent on the Internet these days and I particularly don't want to have
it on my Email List sites.
If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email
Lists, please make a Contribution to keep it that way!!

I have been looking at your Kolb with a full enclosure, I was looking for ideas
on how I was going to do just that. The question is what kind of cruse speed
you are getting on that bird with wheel pants, enclosure, strut and wheel leg
fairings, and what engine are you using? A question from a newbie to the site.

| Subject: | Bing 54s & primers |
My ancient Rotax 503 was modified by the previous owner from one Bing to a
pair of Bings. The original Bing has a cable to the enricher, but the other
only has the little handle to activate, and it's really cranky about
starting even with both activated. The previous owner said that it will
start easier if I install a primer (and the engine seems to agree, based on
'dribble priming' it).
So, I just ordered a primer plunger kit (made for Mikunis) , but only one
of the carbs has the primer port in the body. Anyone out there with any
experience using manual primers that can tell me if priming both carbs will
materially improve starting? Should I just bite the bullet & drill the
other carb for a primer fitting?
Thanks,
Charlie

Charlie, I think you'll be fine with a single carb having a primer port
since all the primer does is get fuel to the engine before start up so you
don't have to wait for the pressure pulse fuel pump to move fuel to the
engine. At worst the engine might run a little rough for one or two
seconds. Are you going to convert the other carb to a cable pull enrichener
?

It's hard to start even when the enrichment cable is activated, and the
enrichment lever is flipped on the one without a cable. Also, the
airframe was set up for only one cable, so it seemed more sensible to
just add a primer. Maybe I'll try putting the enricher cable on the
non-primer carb, and feed the primer to the one with the port.
Thanks,
Charlie

I measured 290 pounds static with a Rotax 377 turning a 72" IVO prop. There was
a slight amount of tailwind that day, so I suspect that number is slightly inflated,
but I'm sure it produces at least 250 pounds. It jumps right off the ground.

| Subject: | Bing 54s & primers |
I never had the need for a primer on my two strokes, both Cuyuna and
Rotax. Engines would start with no problem well below freezing. Same
or similar carbs as mounted on snow machines (snowmobiles). Reckon it
gets pretty cold, in their environment, at times.
If the engine and fuel system is in good shape, it will start with the
enricher in a couple pulls, and even quicker with an electric starter.
When the enricher is pulled it opens a valve to dump the fuel stored in
the enricher well, doing same thing a primer does. Then the engine is
pulling fuel from the idle jet and the enricher jet plus allows a little
more air through the carb.
Before I'd spend the money and hang another gadget on my airplane I'd
make sure that the carb is doing what it is supposed to do, especially
the enricher system. Could be you aren't getting that initial dump of
fuel from the enricher well on start up.

That's a good data point to know. None of the docs I've read mention the
enricher acting like an accelerator pump when it's activated; they just
talk about the plunger opening up a second, richer fuel path when the
throttle is closed. I'll pull the filter assy & look for a squirt of
fuel when it's activated.
Thanks,
Charlie

Been 25 years since I had a Rotax 2 stroke. Forgot to mention a couple
things that are important:
-In order for the enricher system to work correctly, the throttle must
be closed. If the throttle is cracked it defeats the enricher system.
-Make sure the enricher seal is in good shape. They didn't last long
back in my day. If they leak they'll drive you nuts trying to figure
out why your engine ain't runnin' right.
-The carb float bowl should be full prior to attempting a cold start.
Fill with the primer bulb or an electric fuel pump. Getting rid of the
primer bulb and installing a Facet pump will take care of filling the
float bowl and eliminate a probable problem.

Yeah! Make sure the enricher jet is not blocked.
If the enricher jet is blocked, fuel cannot fill the enricher bowl.

Not an accelerator pump, but does pull all the fuel out of the fuel
enricher well on initial engine turn over, if the throttle is closed.
You won't see a squirt of fuel when it is activated, and if the throttle
is cracked, it defeats the enricher system.

That's a good data point to know. None of the docs I've read mention the
enricher acting like an accelerator pump when it's activated; they just
talk about the plunger opening up a second, richer fuel path when the
throttle is closed. I'll pull the filter assy & look for a squirt of
fuel when it's activated.
Thanks,
Charlie

If the engine and fuel system is in good shape, it will start with the
enricher in a couple pulls, and even quicker with an electric starter.
When the enricher is pulled it opens a valve to dump the fuel stored in
the enricher well, doing same thing a primer does. Then the engine is
pulling fuel from the idle jet and the enricher jet plus allows a little
more air through the carb.
Before I'd spend the money and hang another gadget on my airplane I'd
make sure that the carb is doing what it is supposed to do, especially
the enricher system. Could be you aren't getting that initial dump of
fuel from the enricher well on start up.

Subject: Kolb-List: Bing 54s & primers
My ancient Rotax 503 was modified by the previous owner from one Bing to
a pair of Bings. The original Bing has a cable to the enricher, but the
other only has the little handle to activate, and it's really cranky
about starting even with both activated. The previous owner said that it
will start easier if I install a primer (and the engine seems to agree,
based on 'dribble priming' it).
So, I just ordered a primer plunger kit (made for Mikunis) , but only
one of the carbs has the primer port in the body. Anyone out there with
any experience using manual primers that can tell me if priming both
carbs will materially improve starting? Should I just bite the bullet &
drill the other carb for a primer fitting?
Thanks,
Charlie
