Happened to my Husky..Your mower is equipped with the EPA positive shutoff electrically operated valve on the bottom of the carb..it is designed to stop overflow of gas from the carb when the float sticks.. however when it fails the gas now flows back through the carb and into the cylinders and eventually filling up the crankcase and cylinders.. In stead of to the ground...You can replace it but eventually it will fail...the easiest and best fix is to put a easy to get to shut off valve between your tank and carb..When ever you shut your mower down for ANY reason turn off that valve before shutting it down..put mine on two years ago and hasn't failed me yet...Just need to remember never shut the mower down with out turning the gas flow off....NEVER....it may not fail but when you least expect it WALA oil in the gas...best is to shut the gas off and let it run for 20 seconds or so then shut the mower down..this assures no gas in the carb system cannot get into the oil...hope this helps pass it along to your friends as all newer motors are required to have them...good luck.

SOURCE: Gas entered the exhaust system and then oil reservoir. I got the gas out exhaust change oil. Mower runs but in question is gas still entering both places.

the little solenoid on the bottom of your carb is letting gas flow while it is not runnung.therfore gas gets into your oil.About an 80.00 part..or you could just turn your gas valve off when your done mowing.but still you would have to eventually replace that part.hope this helps

SOURCE: riding lawn mower keeps flooding

It sounds like the inlet needle seat is not closing all the way,allowing fuel to overfill the carburetor.The inlet needle seat may have dirt in it.You will have to remove the carburetor bowl and check for dirt or debris in bowl,if so remove the float assembly and check for a peice of dirt between the inlet needle and seat.If there is none you may have to replace the carburetor or rebuild it with a carburetor kit.You should also chang the engine oil because the overfilled carburetor drains to the crankcase,filling it with fuel,check the oil level and see if it is high,that would indicate fuel is in the oil.Hope this helps

SOURCE: i need an owners manual for a murray riding mower.

First off, confirm that the tractor is in Neutral and the deck is not engaged. You also need to be on the seat, and in some cases your foot must be on the brake. Then try it.

If by "jump" you mean essentially connect one end of a jumper cable to the battery power coming to the solenoid, and the other end of the SAME jumper cable to the 6 gauge (+/-) wire on the other side of the solenoid that goes to the starter, and it cranks, this means one of two things.

More than likely it is the solenoid that is bad, but the only way to confirm this is to make certain that when you turn the key, it sends power to the small (18 gauge) wire on the solenoid. This is easy to check with a test light.
If power is goes to the solenoid when the key is turned, but the engine fails to crank then the solenoid is bad.

If no power is there, then the problem has something to do with either the ignition switch or ignition wiring, or more likely it is a failure of one of the safety switches, under the seat, transmission in gear, sometimes if the deck is engaged, or other.

One way to confirm that the problem is with a safety switch or ignition switch and rule out the solenoid would be to jump a wire directly from the positive terminal to the small wire on the solenoid that comes from the ignition. If this causes the engine to crank, then the solenoid is OK.

What is wrong when oil mix with gas and the riding lawn mower will not start?


Riding mowers are usually straight gas, not mixed. If you accidentally put mixed gas in it the carb, plugs, and engine may be gummmed up. Clean, flush, start with fresh gas, and you should be OK

How could gas be entering the crankcase of my Husqvarna 48" riding lawn mower?


Sounds like you have a hole 'burnt' in the piston top allowing fuel combustion mixture (normally compressed above the piston) getting down into the crankase or that the piston rings are shot allowing the same thing.
As the piston is continuously moving, the reverse happens giving oil at the intake or carb.

. Looks like a strip down, good inspection and rebuild of engine required .

all riding lawn mowers that I am aware of do NOT use mixed oil/gas. they use only straight gas in the gas tank and they have a separate tank for oilyou need to look online under the manufactures web site under manuals and or service files or call the dealer.

What type of oil and gasoline do you nee d to run Craftsman 6.5 lawn mower?


generally all 4-cycle lawn mower engines are tuned to use regular unleaded gas ,(I personally use mid or high grade unleaded)....and for engine oil use strait 30 WT engine oil...... I often put a dash of fuel system cleaner in each gallon of lawn mower gas,it is not absolutely neccessary but seems to help moisture stay out of gas..(DO NOT USE HEET or other methenol based fuel additives for this can cause overheating or scoring of piston and cylinder...but rather use a petroleum based additive,this allows the small amounts of moisture in fuel to pass through the carbeurator without clogging filters or fuel system for smoother running)..also...if you put lawn mower up for winter it is always helpful to use a fuel stabilizer such as "STABIL" or other such products (follow directions for use) and be sure to change the crank case oil in the spring before using....this will give you much longer life from your lawn mower...
Keep air filter clean!!!..... Happy mowing!!!....so, the answer?...regular unleaded and 30wt engine oil...if you would like..they have special engine oil for 4-stroke engines at most hardware and walmarts n such...but is just expensive 30wt oil... Enjoy your day,Todd

Can I use leaded gas or only unleaded


check with your owners manual. But as a former lawn professional, I only used Premium fuel in my Scag zero mowers. You should however use ethonal free fuel if you don't run at least a tank a month through it or you can buy Marvel Mystery Oil as a fuel additive to help keep your motor clean and running smooth. I use Marvel Mystery Oil in the boat, mowers, and 4 wheelers. Works great. Ethonal free gas is hard to track down so this is a great alternative.

Murray riding mower 12.5 hp briggs & stratton spitting oil & gas out of carb & muffler when trying to start


Drain oil... it is full of gasoline due to a bad float pin and rubber gromet in your carb. When your float pin and gromet fail, gas just keeps flowing into your carburetor, eventually flooding your motor with gas and oil mix.

Gas/ oil mixture


If it is a riding lawn mower it is probably not a two cycle engine so there would not be a gas oil mixture. It must be a 5 horse power or higher so it would use straight gas. I hope this will help you. donnyb60
