<DIV>Actually if it was aluminum to aluminum, TIG, not MIG, would
work...there's no weld that I'm aware of that will attach brass
to aluminum...</DIV>

welding was in jest ;-)</DIV>

size=2>Adrian,<BR><BR>Mig Welding might work...I don't know...I
always thought that MIG<BR>welding was for aluminum and
Steel...like thin sheets or<BR>tubing...Stainless steel sinks and
the likes are MIG welded. While I<BR>think MIG welding would work
on a Header if you were good enough to do<BR>it, I don't
think MIG is what you would use to put the Brass insert
back<BR>into an Aluminum casting. The only thing you might be able
to do is<BR>create a small mechanical stop as you melted the MIG
"wire" over the top<BR>of the brass fitting. The weld would not
penetrate down into the joint<BR>between the brass Injector Tube
and the Aluminum head. Also MIG is very<BR>critical on having the
surfaces clean and dry. It if difficult to get<BR>down in a hole
that is about 1/8" diameter and clean it.<BR><BR>I know there are
some welder types out there. I'm not a smart guy on<BR>welding. I
just know that there are different processes needed when
the<BR>metals are different types. If it was Aluminum to Aluminum
then I think<BR>MIG would work...but I don't think it's the best
for that situation...I<BR>think Mig is used when you are building
a Bead on the external surface.<BR>Not trying to get material into
a recessed hole. I would think a Sweat<BR>joint like a plumber
uses on copper pipe would be a better situation.<BR>The
Filler rod or solder or what ever would penetrate the joint
down<BR>into the recess and make a mechanical connection down in
the hole.<BR>Welding a small bead over the top of the brass nipple
with a MIG welder<BR>may hold for a while but I think it
would fail in short order...<BR><BR>Sorry just not enough welding
info in my brain.<BR><BR><BR>Troy<BR><BR><BR>-----Original

[NSRCA-discussion] YS-160 round 1...ding,
ding<BR>><BR>><BR>>Jason,<BR>><BR>>Regardless of
the peanut galleries comments here is the
skinny.<BR>><BR>>There are two parts...the black plastic
check valve....and then the <BR>>Brass Injector that goes into
the head. The black plastic part can get <BR>>loose, IF the
injector fuel line is allowed to flop around. This is
why<BR><BR>>it has a clip on it. Some folks will remove the
clip and the fuel <BR>>tubing is allowed to flop. Also some
folks seem to thing they can <BR>>remove the black plastic
check valve and re-install it. Nope the <BR>>Plastic goes on
one time and to remove it the plastic breaks out and <BR>>the
hole is not larger from the barb damage.<BR>><BR>>The idea
is to not mess with it.<BR>><BR>><BR>>There have been
a few cases of mostly early 160's and mostly a couple
<BR>>years ago when the brass nozzle came out of the head. I
know of 3 of <BR>>these and one was in Japan, one in Australia
and one in the USA.<BR>>Extremely rare, but clean it up and yes
I have been told JB weld will <BR>>fix it. My understanding is
that this nozzle is pressed in with some <BR>>kind of adhesive
at the factory. So the JB weld is the same kind of
<BR>>thing....You don't have that problem.<BR>><BR>>If
the engine is allowed to hit the cowl of the model sometime the
<BR>>black plastic check valve will get knocked around....If it
gets loose, <BR>>just remove it and hook the fuel tubing direct
to the injector nozzle. <BR>>It will work fine. The check valve
is there for long extended idles, <BR>>and quick throttle
ups.....Think F-07 Double Avalanche. The check
valve<BR><BR>>prevents a burp on throttle
up.<BR>><BR>><BR>>If you engine is set properly you won't
get the burp anyway...but if <BR>>its just a touch lean
on the pump...then a tiny air bubble can migrate<BR><BR>>back
into the injector fuel line. This is because the valve cover is
<BR>>the air box...and is under pressure...so the high pressure
keeps the <BR>>fuel from coming out of the injector until the
valve on the engine <BR>>opens. When the valve opens the pump
gives a squirt and the fuel comes<BR>out.....<BR>><BR>>At
idle the engine is not using much fuel at all....and the injector
<BR>>will leak a little fuel into the valve cover area....If
the engine is <BR>>too rich (pump)...this is what causes it to
get a rough idle. If the <BR>>pump is too lean then there is
not enough fuel in the line and the <BR>>pressure in the line
is lower so the air box pressure pushes the fuel <BR>>back in
the injector line and right at the very end of the in injector
<BR>>line forms a little air bubble.<BR>><BR>><BR>>The
black plastic check valve prevents this from
happening.<BR>><BR>><BR>>So the long story aside if its
flopping around pry it off with a large <BR>>flat blade screw
driver, just slowly inch it off...then hook the fuel <BR>>line
direct. It will work fine.<BR>><BR>>By the way the new 170's
have a different clip on the injector line <BR>>that keeps the
fuel tubing from flopping around. This keeps the black
<BR>>plastic from turning and getting loose on the injector
nozzle.<BR>><BR>><BR>>The peanut gallery can now continue
their comments.<BR>><BR>>Thanks<BR>>Troy
