Find the engine number of your 5.5 HP engine and pass it on here. That way I can pass you the correct manual. Having said that... Remove the float bowl and clean the debris out of the bowl and the orifice in the threaded area where the bowl nut screw into. The orifice is blocked in the threaded area. You need to clean the pin hole out in the orifice. Break off a round toothpick and use the "BROKEN end" to clean the orifice while it is installed and some carb cleaner. DO NOT stick anything in the hole as it usually breaks off in the hole or expands the hole causing other problems.

Remove the fuel hose from the carb and make sure your getting fuel to the carb. Also make sure you see fuel flow into the bowl area with the float bowl removed.

Reassemble and test.... This should get your engine going again. If not... I need the engine model type and serial number to get the information you will need. Do not abreviate the numbers.

Thanks for choosing FixYa,

All of a sudden started backfiring. What could be the cause?

A Back-fire or backfire is an explosion produced by a running internal combustion engine that occurs in the air intake or exhaust system rather than inside the combustion chamber.

In engines with a carburetor, this is often caused by the carburetor being gummed up from unused fuel. Many people don't know that new gas with ethanol can't sit unused for months without going bad. If you look in a tank of gas that has been sitting a while, there will be puddles of gunk on the surface. That gunk really clogs up carburetors, making the engine not run properly.

Usually this can be fixed by dumping all the gas, taking off the carb, and cleaning it out. Or you can take it to a small engine shop if you aren't good with tools. For all small engine tools (lawn mowers, tillers, etc) you need to let the gas run out before storing them if they will sit unused for more than a few weeks, or you will have to clean the carb again.

Hope this info helps!

Will not stay running

Hi. You still have junk in your carb. Get a can of starter fluid and a helper. As you run the engine have your helper give it a squirt of starter fluid directed at the air intake until the engine runs smoothly. J.

I have a 8hp briggs and stratton model 190432 with a carb 390323 that gas just pours out the bottom can anyone help?

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.

Gas in tank wont start unless put gas in carb-then

Hi, being a tiller theres a good possiblity that the line is glogged and if theres a line filter it could be plugged also. Another source of clogging is from old gas, ti can become a little varnished.

Remove the line clear it with compressed air or other source, drain the tank and if theres a line filter - replace it.

Another source could be the air filter - usually a sponge. Replace this as well or clean in a varsol bath. squeeze it out dry, then apply some oil to the input side - helps to catch dirt, etc.

USE safety precautions .

Wont run, not getting fuel. disconnected fuel filter, still nothing. Can spray a shot of carb cleaner directly into carb, and will run until it burns the fuel then dies. Check and getting good spark.

you say it's not getting fuel? when you bypassed the filter was gas coming out of the fuel line right where it connects to the carb? If it runs on ether, carb cleaner or pouring fuel in the carb then your problem wont be the the carb or motor it will be something like a cracked, dryrotted or pinhole in the fuel line. Or something restricting the flow from the tank to the carb.

without knowing if its a briggs and straton or tecumseh engine ( I assume Briggs) the carb is where the throttle and gas line connect to. carb will need to be rebuilt most likely and tank will have to be removed to be cleaned. you can email me and I could do it for you I am in wisconsin kerryjonjon at I am the most reasonable in this area. I could do carb and tank if you want.

5 hp Briggs and stratton wont run on a MTD tiller.

I had the same problem a few years back. Check the rubber elbow coming from the gas tank to the carb, it's probably cracked and sucking air instead of fuel from the tank.
