[@croquest8749]

Faulty gas cap (not breathing) will build pressure and that pressure will push your needle valve down and through the carb up into the intake . Just happened on mine the other day.

[@JohnsonsSmallEngines]

A faulty gas cap does just the opposite and creates a stoppage of the fuel flowing eventually causing engine to starve of fuel from carburetor shutting machine down. The engine creates the vacuum needed so the carburetor can pull fuel.

[@croquest8749]

@@JohnsonsSmallEngines Yes it was doing that also and after l parked it and no vacum. It was shooting up through the carb like it was being pumped. Changed the carb and was still doing it . Changed the cap and it stopped. So l don't know guess will see if l find gas in the engine next time l go to use it.

[@richardoky]

A little trick I discovered : take a carburetor and hook a 1/4" hose to it. hold it old it up right and blow and you should be able to tell the air is going through it. Now turn it upside down and you should not be able to blow through the hose. When turned upside down the float should close the flow.

Clean and free up the carb shut-off valve and also add an in-line shut-off valve just in case.

[@alexanderbarrios7813]

Thank you so much for the video. I do have a question. I followed all of your steps and cleaned the carburetor. I filled the oil and the fuel tanks.

I have almost that exact tractor that I bought new in the fall of 1996: Model 917.256890 Serial 092596D (Sept 26 1996) Original engine B&S 28N707 0173-01 960830ZD (Aug 30 1996) I replaced the engine in 2005 due to catastrophic failure (broken connecting rod). The replacement engine - which it still has - is B&S 28N707 1026-E1 991102ZE (Nov 2 1999). Its interesting that the replacement engine evidently sat for over 6 years before I purchased it. Around 2010 it began to experience hydro lock after sitting between uses. I tried rebuilding the carb several times without success so I installed a fuel shut off and now just run the carb dry at each shut off. No more issues. I completely rebuilt the tractor in 2020 during Covid as the frame was badly cracked in the front - probably from years of using it in the winter with a small plow blade. I was lucky to find a vintage parts tractor (no engine) with a perfect frame. I also rebuild the hydrostatic trans (Hydro-Gear 310-0500) to replace the seals. The current engine has 390 hours on it and I estimate the entire tractor to have over 700 hours in its almost 29 years. Paul (in MA)

[@jtltet]

Great video!! I just had this happen to my mower yesterday. After it happened and I tried to start it, it didn't try to turn over. It just made a high pitched whining or whistling sound. Did the gas cause an issue w/ it not trying to turn over or could it also be a starter or solenoid issue that would make that sound?

[@JohnsonsSmallEngines]

What can happen is the gasoline flows from the tank through the carburetor and into the engine oil then it fills up and goes into the combustion chamber where the piston is and if both valves are closed, and you go to start the engine, you will have a liquid lock where the piston will not move because the fuel is in the way. Your starter solenoid most likely is OK. You will need to remove the spark plug. Make sure the spark plug wire is not near the spark plug hole and spin the engine over to relieve the fuel that is in the cylinder. I would suggest spinning the engine over by hand and make sure you have many many rags or something to catch the fuel that will be coming out of the front spark plug hole. Once you have all the gas relieved from the cylinder, you can go ahead and try to crank the engine with a starter, but as I said, be careful where the spark plug wire is sitting so you do not catch any fuel on fire if you do crank over the engine while the spark plug is out.

[@jtltet]

@@JohnsonsSmallEngines Awesome!! Thank you so much.

[@rscotta831]

After draining the crankcase, do you think I need to air out the crankcase's intake, with a leaf blower, to get as much gas to evaporate as possible? Or should an overnight oil drain suffice?

[@JohnsonsSmallEngines]

The overnight is oil drain is good.

[@rscotta831]

@@JohnsonsSmallEngines After refilling the oil, should I then mow the lawn once, then change the oil again to completely rid the gas in the crankcase?

[@JohnsonsSmallEngines]

It wouldn’t be a bad idea to drain it twice but it is not needed especially if your able to drain the engine all night you should be ok. If you do have a oil filter and you are draining the engine twice, remember to also change the oil filter again.

[@chuckr.]

Thanks so much for this video. I thought my lawn mower was done. It was fine at the end of the season but when I started it up this year it was smoking. When I tried to engage the blades it started sputtering and stalled out. I thought I was going to need a new tractor. I had gas in the oil too. I drained the oil, replaced the filter and got a replacement carb from Amazon. That spring was hard to get. I did get a little bend but straightened it out. I started it up okay but now it seems that it runs rough on high RPMs. If I lower the throttle it starts running smoother and I can slowly increase RPMs. It still not right. Do I need to replace the spark plug? Any suggestions? Thanks again for this video.

[@JohnsonsSmallEngines]

I cannot diagnose a symptom without seeing the engine while it’s running and I have no luck with aftermarket carburetors for the larger Briggs and Stratton engines. I would suggest trying to rebuild the carburetor that came off your engine if it is an original OEM “ original equipment manufacture”. Yes I would replace the spark plug, and fuel filter and the air cleaner if needed.

My Ariens 42 with 18.5 hp has acted like the valves were not adjusted correct or broken compression release and won’t turn over to start with brand new battery and starter. So I pulled the valve cover and there must have been a couple ounces of gas in it. So smelled the dip stick and smelled strong of gas. So maybe it has been filling up with gas in the cylinder and won’t let it crank over to start. But when I would get it running and if it stalled from grass being so tall then I go to start it again and it won’t turn over fast enough to start. So hoping it’s just stuck carb hydro locking it and not the compression release. I can turn it over up top by hand but put my impact on the crank bolt up top and it won’t even turn the motor over but has no trouble loosening lug bolts on my cars. So going to I guess pull the carb and take a look. I run alcohol free gas but don’t put any Stabil in it for winter non use months. Any suggests anyone please feel free to reply.

Hello I too am having similar issues with my 25 year old Mastercraft lawn tractor with 15.5 hp Briggs and Stratton engine. My question is what brand and grade of oil 10W30 or 5W30 would you use for such an old tractor.

[@JohnsonsSmallEngines]

My opinion, the brand of oil doesn’t matter as much as the API rating which at the present is SP. Just make sure the oil has that on the back of bottle. Depending on where you live would depend on what viscosity you use. Normally you can find that in your manual for your machine online. In my area I use mostly 10w30.

I have the identical engine and where the engine mounts to the frame the bolt holes are worn oversized any suggestions on how to fix it ?

[@JohnsonsSmallEngines]

The easiest way is drill the holes in the block out so you can slide bolts through then you will need longer bolts so you can use lock nuts on the other side. Get some large fender washers for underneath the frame and bolt engine tight. The proper way would be, remove engine, weld up the frame where the holes are enlarged and drill the holes back out to correct the issue but most DIYers will not have a welder. The first way will work.

[@JohnsonsSmallEngines]

To answer your question with a question. What do you consider is “using a lot of fuel”. That question really cannot be answered correctly as you would need to know what other 12hp engines are consuming. I cannot tell you what they consume as there are so many different variables. If the exhaust coming out is clean burning and engine is running smoothly at full throttle. I would say, it is what it is.

Hello, I replaced the carburetor and changed the oil. After doing so the engine will start up, but only last about a minute. It sounds like it runs out of gas when it dies. I checked all fuel lines and gas cap but for some reason it keeps dying. When I check the oil it definitely still has gas in it. Do you mind helping me with this?

[@JohnsonsSmallEngines]

Almost impossible to diagnose. When home not in front of the machine but I can say you must make sure you’re getting good flow of fuel from the gas tank to the carburetor so I would check that. Also, if you have a electronic fuel shut off solenoid, I would make sure that that is working. Not sure how good the carburetor is that you bought if it is OEM or not original equipment manufacturer? Or I would definitely change the oil again until you know there is no fuel in it.

@@JohnsonsSmallEngines Okay, thank you for the fast response. I realize it's not very helpful to not include what the engine is lol. It's a troy bilt pony, with a Briggs & Stratton 17.5hp. I am very new to working on engines so your help is very much appreciated. I seem to have good flow. I thought maybe the cap wasn't letting air in and creating negative pressure, but even with it all the way unscrewed, it has the same issue. The carb I replaced was leaking gas out of the breather tube, after replacing it, the tank holds gas without having to use the shut off. The replacement was off Amazon. I will change the oil again.

@@JohnsonsSmallEngines For a more concise explanation - The carburetor was leaking gas from the breather tube, and the oil had gas in it. So I replaced the carb and oil. Now the gas stays in the tank. However, when I start the engine. It runs for about a minute, then it slowly putters out. Almost like it's out of gas. If I wait about 30 seconds, it will start up and do the same thing again. - Extra info, when the engine is started in choke, it puffs black smoke with each stroke. -

Does it have a fuel shut off solenoid underneath the carburetor? If it does? Check to make sure it’s working. You may also have a bad new carburetor. Again this is all I can help you with without being there.

@@JohnsonsSmallEngines It does have a solenoid underneath. I am hearing a click when I turn the key, and the wiring all looks normal.
