Oil pouring into carb..

I have a Murray rider mower. It was running real bad, kept stalling and wouldn't keep running. I took the carb. off and cleaned all the parts, the float was full of all kinds of stuff. I put everything back together and started the mower up. Oil, I assume, was pouring out of the hose that connects to the engine and the air cleaner. I thought it might be the carb. spray I used to clean thge whole thing, but it was way too much than I had sprayed in there. So what did I break? I'm sure this is something major.

Thanks, Dave

Is the oil level overfull? Is the oil thin and smells like gas? If so, your carb is leaking gas into the crankcase.

You definately have a gas leak problem as the oil capacity for your engine is at most 48oz. Fill the oil to the proper level with decent, but in expensive oil. Run the engine for about an hour, under a load, then drain the oil and refill with a good brand of oil. I don't know how old or how big the engine is, but if not too old, maybe use synthetic oil.
First of all FIND THE GAS LEAK!!

Take the old oil to an auto parts store that takes used oil. It is illegal to put it in the trash to my knowledge, not to mention bad for the environment.

The gas will return to the new oil if you don't fix the leak. The needle is not seating into the seat in the carburetor. I'd say clean the carb well, make sure the float moves freely up and down, replace the needle, and clean the seat area well with a Q-tip soaked with carb cleaner.

I did clean the carb, real good. I put some new oil in and started her up, still running a little strange. I think there is still some oil in the carb, as I only ran it for about 2 mins.. I will have more time this afternoon, and will clean out the carb. again, well first I will let it run a bit longer to see if I need to. I'll let you know what happens.

Thanks again for all the help, Dave

I love these forums!!!

PS, the used oil,are you saying I can not try to feed it to the barking dog next door? Just kidding!!

I am having the same problem. I know very little about small engines, and have never worked on a carburetor. I have a 5 hp Briggs and Stratton only a few years old. It has gas in the oil. When you say Needle is not seating properly, where is the needle? I think the float is in the little bowl at the bottom of the carb. Can I just remove the bolt holding the bowl on?

Yep, drain the gas or clamp off the fuel line and remove the bolt holding the bowl on. You'll see the float there. There may be a lot of crud in the bowl and if so you'll need to clean it well with carb cleaner. The float is held on with a pin. The needle will be clipped to the float and you can clean/inspect it by removing the float.

Gasket?

When I remove the bowl and clean everything up etc., will I need a new gasket to reinstall the bowl? How will I know what gasket I need? I got these numbers off the OHV of my motor, but I am not sure what they are. 020719 FD, 120402 0200 E1.

You probably won't need a new gasket since most of the time the old bowl gasket is in decent enough shape to reuse on newer engines. The numbers you gave are the model, type, and code numbers.
