<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>

<DIV>Just so it is known, I believe the original comment about MIG 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 Message-----<BR>From:

Noticed that there is no fuel line keeper, so gotta order <BR>>one of

low<BR><BR>>end solved the higher issue instantly too, thanks again! I'm
hoping<BR>that it only moves cause of the lack of the keeper, so we'll get
that on<BR>and go from there. Worst case is eventually we'll plug the line

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
