Craig Dow: Thank you so much! I cleaned the carb, replaced all gaskets and primer bulb and it still wouldn't prime. Tried your double gasket fix and it worked perfectly! Thanks again for sharing your expertise. 

John Schmahl: Putting in the second gasket worked like a charm. Owner of repair shop where I bought the gasket warned me not to tighten the bolts to the carb too much because the primer base would be warped which, sadly, I had already done. Cranking down on the bolts to get a good seal is a recipe for trouble.

grasscutter88: Will this cause it to not want to run either? My primer just pushes air and it starts and runs for 3 seconds and shuts off. I'm pretty sure it's not the carb cause I took it apart and cleaned it and ran a wire thru all the passages.

Mr Guillermo Costecho: Thanks worked like a charm

Char Dunstan: hi i have 3.5 hp briggs stratton pump primer type that wont prime ie squirt fuel can you help please 

luke b: I have same engine quantum 50 briggs stratton , can't start it pops out carb , I did remove head and notice when piston at tdc I could spin the valve easy with finger ?? My question is would this make not start and kickback
Thanks , oh and I tyred starting it with the blade removed if that make difference 

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!
Thanks!

Josh Davis: Pretty smart, I can't believe I never thought of that. I subscribed to your page, thanks for the tip.

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?

Brandon Medice: Can you start without primer?? 

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

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?

oldvolkz: i replaced my gasket but it still wont prime?

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.

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.

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

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.

JEREMY FOUNTAIN: Needle and seat in the Carb is jacked up
