The problem that you are describing is caused by intake valve not seating correctly. I see this problem on engines that have many hours of use or lack of service. You may be able to grind /reseat /adjust valves but usually requires new guide, valve and spring. Enjoy

A lot of time when the small motors on these push mowers surge it is a governing spring that is weak or broke. It does not hold enough tension and causes the valve to fluctuate. I have fixed this many time for a relatively cheap amount (under $5).

SOURCE: I have a 8hp briggs and stratton model 190432 with

I had the same problem with my 190402 tiller engine (on a 1978 Sears RT-8 that my brother gave me). The carb leaked like crazy when I got the tiller, so I rebuilt the carb. Bought a new float, but the old one was fine (the hot water test you can read about if you do a Google search).

After rebuilding the carb and checking the float system (carb apart, hold carb top upside down with the float and needle installed, then blow into the gas inlet to see if you can pass some air. My carb top passed that test, and I guess it's a valid test. Never tried that one before . . .

Put the engine back together, and the carb leaked gas fairly steadily, but at a much lower rate.

I read a comment from someone that sounded flat-out wrong, but the Briggs rep. who responded to my email said to do the same thing. In fact, the rep. sent me a Briggs document showing what to do. It's like a tech sheet. Nice customer service (and I never even bought their stuff directly!!).

The problem I had was with the emulsion tube and its seat inside the carb. You probably have the same problem. You need to buy a new one emulsion tube because you are going to ruin the old one. The tube seats against the carb at a place that is below the fuel level -- can you see the problem?

Take the old tube, grind off the threads (I used my Dremel tool). Get some lapping compound (I used water-based stuff from the local auto parts place). Put some compound on the seating part of the tube, insert the tube, and use a screwdriver to lap the tube against the carb seat. Check it every once in a while. I think I probably did it for 3 to 5 minutes, not very aggressively, and added compound one time.

Look for a smoothness to the carb seat. Thoroughly clean out the carb. I used spray carb cleaner for the initial rebuild and the lapping compound clean-up. Put the carb back together and check for leaks before starting the engine. Start the engine, and hope that the leak stays gone.

I haven't had any problems yet, and I've used the tiller for about 4 to 5 hours so far. Maybe 6 or 7, but I've been using it for about a month off and on.

If you want me to send the pdf version of Briggs' document regarding this fix, send an email to me at Just put in the subject line: Briggs Carb Fix. I'll shoot you a copy no problem.

Good luck.

Briggs and stratton quantam 6.5 hp fires but will not run

Check for a clogged air filter.Try starting it without the air filter installed. Check for loose wires to the spark plug and ground. I am assuming there is gas in the tank, but does it get to the carb? Check the gas line, is it blocked? Is the carb leaking?

If the float don't float, the needle valve stays open and gas runs into crankcase.

If float floats (has no gas inside) then the needlel is probably worn and needs replacement.

Have to choke to keep running

this is not hard to do here is what you need , 1 can of carb cleaner anykind will do , a 10 mm rench to remove the bowl 7/16 socket . now remove the carb take a good look where the spring is before you take the carb off it muct go back in the same hole , now that you have it off take the bowl off remove the float place to the side here is the fun part look in the carb you will see some small hole spray them this will clean all of the old gas out if you can let it set for about 10 min then do it again blow out with air if you have one nothing else to do but reinstall this works most of the time ...Good Luck..
