Milosz Ostrow: Can't understand a word that was said -- just wind noise. Cover the
microphone with piece of open-cell foam, or at least some fuzzy fabric if
you're going to record in a windy location.
Bruce Arnold: I done this step on the briggs I have and still came up with nothing,
I tightened the bolts easy at first then maxed out the tightness fearing I
would strip the base..I also just for kicks after this put silicone at the
base of the bulb and let it dry..
Anyway still back to square one I will try a different air filter base now
just to help my curiosity on maybe its in the carb..But I can spray carb
cleaner in that little hole on carb and sure enough it comes up the tube in
venturi so..Any other ideas? Let me know!
Luis Jr Magaña: when I prime it is not stiff like fuel passing more like air, this is a
brand new mower from briggs. Its so hard to start the mower matter fact
have not gotten it to start yet, could this be the issue?
Josh Davis: Pretty smart, I can't believe I never thought of that. I subscribed to your
page, thanks for the tip.
Brandon Medice: Can you start without primer??
Edward Wilson: My new briggs engine on Murray mower will not start unless I take the air
cleaner off and manually choke the carb (I turn the air cleaner over on it
for temp choke and it starts right up). My old one was the same way and I
was hoping the new one would start after priming like it should. Ideas?
welostourdemocracy: Thanks a million man! I worked on getting my mower to prime yesterday and
today then came in to find some information on it since I could not get it
to prime even after replacing the gasket. I knew it was leaking air behind
the gasket when priming by spraying wd40 around the gasket area and pumping
the bulb but didn't think to simply put in a second gasket until I ran
across your video. Knowing me I would have gotten into making a metal
plate or something which would have taken a lot of time. Instead, I put in
a second gasket which is much simpler and it worked.......thanks again.
Old Sarge: thanks good vid and the link to buy the part cool
wcjcnc: Hey, love all your vids. I was wondering if you could help me. I have a
mower like the one in this vid. It has a OHV engine. I've done EVERYTHING I
can think of to fix this problem but it's still doing it. Here's what it's
doing. I push the primer bulb a few times. Pull the rope. Then it sputters
for 5 or 6 seconds before it takes off and runs like it should. What would
cause a mower to sputter really slowly for 5 or 6 seconds before it runs
right? Thanks for ANY help at all.
oldvolkz: i replaced my gasket but it still wont prime?
ncrdisabled Submarine vet: I have a problem that I need yor help I have a 1972 ariens tiller 5hp that
had a weak spark . I am a disabled vet so its a little had to understand
some things . I tested the spark very week . I opened it up expecting
points but the was the magnatron with some kind of conversion board to
replace the points I do not know what to do at this point. I can not find
the electronic board any where. What do you think?
aecom1: I have a Poulan Pro 625 series briggs and stratton walk-mower. The problem
that i have is that ,it won't start at all. I can see...when I open the gas
cap and prime ...the bubbles coming up in the gas as i prime. I can also
see ,bubbles coming up when the air filter is removed and I'm priming
...from the back of the base-air plate connected to the carburetor.On the
base-air plate it has a groove coming from the primer,and the gasket is
old. Could this cause a no start?
nick l: Is it possible to bypass the primer bulb.
JEREMY FOUNTAIN: Only way fuel can enter the crankcase on that engine is due to bad needle
and seat inside the carburetor or the fuel pump diaphragm is bad causing
fuel to be sucked into the crankcase via the pulse hose. the only other way
would be sabotage
JEREMY FOUNTAIN: Needle and seat in the Carb is jacked up
Razorron90: Lol. I just bought a Briggs 625 and it would prime at first and crank and
run then go dead after about 15 seconds and it did this about 3 times. So
my first thought was it wasn't getting enough fuel to the engine. So I
checked all the gas lines and cleaned the carb. But before I did all that
the primer won't put out any gas so I resorted to google and this popped
up. Thanks for the vid. I knew it had to be something simple.
Grinder Monkey: I got a good one for you. Briggs 8 hp log splitter with extensive overhaul
to pull starter, carb rebuild, replaced fuel pump, HOWEVER every time I
fill the fuel tank, the engine will start but suddenly fuel and oil shoot
out of the crankcase vent that attaches to the air cleaner assembly. The
fresh oil is completely diluted with fuel and I can't figure out how this
could occur. Float and feeder pin at venturi is clear but no fuel seems to
be reaching the float bowl. Would appreciate help.
ncrdisabled Submarine vet: these are the numbers 100292 0154-02 74050807 any help you can be will help
Grinder Monkey: Your last word was the case for me. The fuel pump was incorrectly hooked up
to the fuel in, fuel out and vacuum lines causing the fuel to exit through
the breather tube. Replaced breather and fuel pump. Additionally the uptake
tube that feeds the venturi was totally clogged preventing proper fuel flow
through the float bowl at all. How it ran in its previous condition is a
mystery. Thanks for the help.
belue7: definately got me scratching my head. lol
JEREMY FOUNTAIN: i would do away with the board and install a new electronic ignition coil
part number 397358
rtzapper: great idea i never thought to double up the gaskets
belue7: No i checked it also got a clean view through. Bulb was ordered from B&S
and is correct primer bulb for that model also.
bondscalper: Dude you just saved me a pile of money !!!!! I bought the carb kit and
replaced the gasket, but no prime !!! The i saw you video and put the old
gasket ontop of the new one and BAMMM The carb primes like new. Thanks your
belue7: awesome tip, i have the exact issue with a mower i am working on! Thank
you, exactly why i subscribed to your channel!!
JEREMY FOUNTAIN: need model type and code off your engine
nick l: how?? Please
Maddog61able: I have a Briggs 15.5 and gas is in the oil system what is the problem. Greg
grease82monkey: U need to put a Facebook link under description
JEREMY FOUNTAIN: Primer passage clogged in carb?
belue7: i did what you suggested and it still does not prime? I also switched the
whole unit out and tried again and it wont prime. Any suggestions? i
appreciate any other ideas you might have. New primer bulb also added.
JEREMY FOUNTAIN: yes
aniorange: A very good and simple tip. I will have to remember that.
FenderGibsonWashburn: This is exactly what's wrong with mine. Thank you
