I have a Yard Machines push mower with a Briggs and Stratton, 190 cc ,ready start ,675 series motor that won't start.

Prior to my problem occuring I had cleaned the underside of the deck and replaced the blade. I turned the mower right side up and let it run a minute or so to shake off the last of the debris. At this point it was probably just about out of gas. Next day it wouldn't start. I believe its a fuel problem because I can pour a bit of gas in the engine and it will run a few seconds and then stop again.

I have fuel going from the gas tank to the carb without any obstructions.

Any help would be greatly appreciated !

carb issue!....take off air filter and spray starting fluid in...see if it catches enough to keep going..if not....take off fuel bowl and inspect and clean...if that doesn't change anything...get back to us and we'll go to the next step:smile:

Welcome to LMF...
You have something in the carb plugging things up... as you say, it runs when you put fuel directly in....
So most likely when you had it over something dislodged and is now plugging things up, possibly the float is off or hanging up, give the whole mower a good jolting bounce, to see if the float will return, if it won't you will need to take the fuel bowl off, and clean out what ever is likely blocking the main jet ... :smile:KennyV

Thanks for the suggestions guys. I apologize for the long time for me to reply. I got frustrated and stopped troubleshooting but I'm ready to give it another go.

Update***

I removed the fuel bowl and everything inside was pretty clean. I cleaned everything anyway and reconnected the float and (?) metal pin thingy ( sorry im a newb...). Still won't start.

I also checked the gas cap as suggested and everything seems good there to.

Questions***

Im not sure I put the metal weight pin back in correctly. It should face the sky and sit up inside a small hole/chamber, correct?

again, any help is greatly appreciated!

WHEN YOU TIPPED IT....IT PROBABLY GOT SOME OIL FLOODING THE CYL......DID YOU TRY THE STARTING FLUID?....YOU MAY HAVE TO DO IT 7-8 TIMES.....ALSO ...PULL THE SPARK PLUG AND TELL US THE CONDITION....THEN CLEAN OR REPLACE IT :smile:

Did I miss something... ? Is there a reason you are suddenly leaving your caps LOCK on?

i was using them on a Mercedes forum....they automatically convert it to small case....is it really that bad?:smile:

It is not that it is BAD, it is just that it removes one of the possible ways to convey any emphasis in printed text...
On most forums it is rarely tolerated & like many have said, it gives the impression of shouting... If some posts are in lower case and others in upper case, the lower case has always 'seemed' easier to read & follow...

I was wondering if I had missed something and you were deliberately doing it, as I noticed it was all upper case in the last few posts you had placed.. :smile:KennyV

no...nothing intentional :smile:

UPDATE****

Still not getting anywhere. I tried the latest suggestion of the starting fluid. I even changed the spark plug for the hell of it.

I give it a good spray, three or four pulls and it runs for 1-2 seconds. I did this about 15 times and gave up.

I hate to trash this thing cause I only got one season out of it but I'm at my whit's end!!!!

Was there any reason in particular you were changing the blade? or was it just dull? Check your air filter, See if it is full of oil. If so buy a new air filter, check the oil, make sure there is no gas in the oil. If so, change the oil.

Yes the needle goes up into the hole as connected to the float.

You don't need to trash the mower yet, even if it turns out to be a repair you can do, it might cost you about $80 at a shop to have done, which is still better than the $200 for a new one.

Thanks for the reply.

Yes, I was changing the blade because it was chewed up pretty badly.

I'll check the oil as you suggest.

My air filter hasn't been on since taking it apart to reach the fuel bowl. Will it not run if the filter is off?

I remember the filter being dirty but not wet when I first took it off.

Since it IS running when you spray something flammable into the carb... Your problem is definitely a restriction of some sort in or before the carburetor...
Don't 'trash' it over a simple carb issue...
Remove & clean the carb ... Go to this site : Small Engine Equipment Troubleshooting, Repairs and Safety

Scroll down until you see your carb on the left side... It will give you easy to follow removal & reattach instructions... it IS as easy as it looks, lots of pictures, can't fail... :smile:KennyV

Forgot to ask earlier: when I remove the fuel bowel from the carb it is dry ( empty) should it be?

No it should have been full ...
Check the needle valve that the float operates... It is either plugged up or the float is stuck... :smile:KennyV

When you tip a mower on the side you have to tip it so the carb is up otherwise the oil will go through the breather and soak your filter in oil

If this mower has the normal square filter on it, go to you rbriggs supplier and buy a 498260 carb rebuild kit and clean it out and replace the needle and seat. Ensure to properly install the new needle seat. Make sure the kit has the needle and seat in it too, Briggs has started taking them out of the kits and are making you buy it separate (what a pain).

My point with the blade was gonna be to make sure the crank wasn't bent or sheared flywheel key if you hit something hard, but as long as the rope is jerking your arm back it should be ok.
