hey guys welcome back to the channel so we got a little deviation from our normal car content
today i was working on the yard and my edger which is this red max gz25n wouldn't start it's
been acting up on me for the last year or so the last thing i did was change the spark plug and it
was working fine for a little bit except the idle sucked i did everything i tested it i took it out
tested the igniter to make sure that i was getting spark against some metal so i took the plug out
i grounded the plug onto some metal and i pulled the string and it actually sparked so that wasn't
the issue i was getting plenty of fuel in here i took the carburetor out cleaned it out as much as
i could but so it still won't start no matter how much i pull and i try on this thing so i decided
to buy a new carburetor to see if that was the issue since it's only like a 15 part so here's the
carburetor i picked up on amazon they have these things all over the place there's a bunch of them
at different price points it's anywhere from like twelve dollars to twenty five dollars for the set
i found one that was kind of in the middle that had all the parts i needed and some that
i didn't so it came with four of these bulbs which these things usually go bad every year
year and a half just from sitting there with fuel in them they start getting hard and brittle and
they break and leak so i got four of those now it came with an extra spark plug which i don't really
need right now but in the future i might need came with two extra fuel filters along with the fuel
filter that's already there it came with a gasket and then two of these little grommets for the fuel
tank i'm not sure what this is yet uh it's some kind of plug or something so maybe it's for the
carburetor inside somewhere but i don't recall seeing that anywhere being used on the actual
machine when i took it apart so i'll see where that goes if i actually need it this is perfect
for me because this grommet on mine has actually been leaking lately i got two of those or actually
three of those now replace it if i need to it came with new hoses which mine are getting a little bit
brittle so that's perfect for the replacement too so other than that i think i've got everything
that i need to get this thing taken apart and put back together so i'll show you guys how to
do that today and hopefully this baby starts after that all right so before we start i'm gonna try to
see if i can flip this thing around by unscrewing these two screws on top and pulling this baby out
it's a little bit tight right here probably just unscrew this side back here
just the stopper to move it out of the way for some clearance
pull that baby out turn it around 180 degrees mount it back in and
pretty simple
next thing we want to do is take apart the existing carburetor so you just unscrew the filter
once you get inside you got to take the torx bit and just unscrew filtered housing
these screws actually hold the carburetor in so you just pull them all out so there's
these long screws right here so now we have access to the existing carburetor
and it's already loose so what you want to do is just unhook the fuel lines
or the it's one of the gaskets that it comes with that we're going to be
replacing so we'll go ahead and just pull out the whole assembly for the fuel so this thing all
comes out in one piece here i'll just set that aside so right here we've got both carburetors
side by side so our new one is basically a heck copy of the one that came out of this thing
but it looks original it's got wire wya 75a on the part number over here so what we're going to do is
we're just going to swap in this one with the new hoses and the new grommet the one thing i noticed
is that the factory one has these clamps which i'm gonna just go ahead and transfer over to here i
might need it especially the one barb that doesn't have the multiple holds right here like the main
line does i think that that's the return line so they just plug that in there and then use this
clamp and on this side since this has got that multiple uh grip barb it just slips right over and
that should be fine once you plug that in it's not going anywhere so the one other part that has one
is over here on the fuel filter it has the clamp here so i'll go ahead and just pop this clamp
off on this side and then use it on the other end i just cut it off throw that away anyways
so we're back over here so i'm going to slip the new hoses and filter into the gas tank
place the grommet in so it's nice and firm i might have to slide it up a little bit
just to get it to measure in with the one that i have here so pop that baby in there get the new
gasket that we have the one that came with just line up the holes here pretty much right there
lines up all the holes so it looks like on mine it had a little some kind of prime thing that
i think that's what what that plug might be right here like if you don't use that
you just plug that hole up but i'll test it out without having that little nipple there and using
that plug so before i get in there i want to put the throttle cable in then just slides right in
turn your deal pull the throttle back line it up and then pull it through so
it's pretty simple there and then you might if you have to make any adjustments to the
throttle cable positioning or the choke you just make it the stopper adjustments now
so now that i've gotten all tightened down before i put everything back together i'm
gonna check the prime to see if it pumps any fuel into the bulb
so i've got feel on the bulb so that's good sign there so what i'm going to do
now i'm going to go ahead and put this cover back on and hopefully it starts
if it doesn't start i might have to swap over that other primer bulb that has that little nipple
that goes into the kind of throttle body or intake manifold thing here so let's see if this works
all right moment of truth i put this little board here so it doesn't spray
fuel all over my floor at least the board will catch it got it on the start position
all right nothing this thing came with a spark plug i'm gonna go ahead and try
that spark plug and see if that's the problem yeah this would really
suck it was just a spark plug even though i just changed this thing not too long ago
so this was an ngk cmr-78 then i'm gonna put in a cmr
6h so i don't know if this is the right one but it's the one that this one came with
so i put in the the plug that it came with and let's see if it starts oh yeah
oh yeah so what i ended up doing was double checking why the ngk plug which was the exact
same one i took out the cmr7h wasn't working so i measured the gap on this guy and it
was like almost .03 and the one that came with this kit that i just bought was like
a .022 gap so i adjusted the gap on the ngk and i tested it and ngk actually kept it running
and started it up it must have been a gap all along at least now i have a new carburetor i
have new hoses and a new grommet which was leaking before so at least i did something
today that was right anyways if you guys found this video useful give it a thumbs up
i know this is not my normal car content but at least it's a motor and i did something around the
house that was useful anyways thanks for watching i'll talk to you guys next time
