Hi new here. Was given this mower not working. Changed coil and gas and got it to start but will not restart. Got it to finally start, dont know how, tan good for about 5 min. Shut it off and could not restart. Any ideas what it could be? Thanks for response

Carbs on those engines are very touchy and I’m guessing the jet assembly is partially clogged. You’ll have to disassemble the carb and clean the jets.

Gonna try that..was debating trying rhat or just replacing it. I did take it apart and spray it out with gum out but didnt check the jets. The fact that it started 2 times made me think it was ok. Il give it a shot👍

Well, new discovery. Last I worked in machine, I put fuel and noticed its empty. I noticed the same last time after working on it but disnt pay any mind. Now 2 times in a row. Take off filter n cover and see the carb is saturated with fuel without priming.. so, any suggestions? I'd really like to know why this is and try to fix. Just for the knowledge but pricing carbs still
Thanks

Dirty carb and dirty fuel tank.

Probable never cleaned the cylinder cooling fins either. Valve adjustment would be a smart move.

All cleaned. Fresh fuel overview- was given to me not running and new coil. Coil was not gapped. Gapped coil, new gas, started then I turned it off. Tried to restart. No go. After about 1.5h, tried again and starts. Runs good about 5-10m. Turne it off, tried to restart. No go. Today when removing carb to clean, notice gass is gone from tank, no signs of leak on machine and carb is saturated in fuel. Going to replace carb, but want to know why the fuel is leaking into carb. My other machine is not like this.

Pull oil dipstick and smell for fuel.

Reread your first post. I think you mention "ran" instead of "tan" because if it tan for 5 minutes the skin so be nearing to becoming leather.

But I shouldn't be surprised with our schools are bad they are at teaching kids. If our schools actually did their job we all would be better educated. I was just shove along until I got into summer school in the tenth grade where I had a teacher that cared. I went from having grades of D's and F's in English to A's the last two years of high school.

Even with auto spell checkers if you use the wrong word it doesn't correct it.

So are you saying that you fill the fuel tank and the it drains into the engine?

This would be a carb problem with the float and the needle not shutting off fuel supply once the carb bowl is full of fuel.

Also check the fuel cap after you run it and then it wont start. Slowly open it and see if air gets sucked in the tank. Your fuel cap vent could be clogged causing a negative vacuum in your tank and starving the engine for fuel.

Also make sure your carb gaskets are all seated correctly. Sometimes if the vent holes are not lined up you will get some funny issues like this (happened to me).

2 times while working on d machine, I put a bit of gass to get it started and work on it. Then next day, or just next time I work on it, no gass in the tank and carb is saturated in fuel. This happened that I noticed at least 2 times. This makes me think the fuel is flowing I to the carb without priming and floods it. I was able to start it 2 times but hard to get started. Then wont start again.
Gaskets good. Made sure jets all open have flow. Cap looks to be good no issues.

Sounds like your cheap plastic carb is clogged/still clogged. Here's a good tutorial for your mower.

Saw anothe vid on utube n it mentioned the needle and seat may be bad and so float doesn't level correctly allowing fuel to keep flowing. I've already ordered the replacement carb so in a day or so should have some results. If it continues after new carb I'm lost. But love workn on it trying to figure it out"

Don't use the mower until you get the carb fixed. Then dump the oil a couple times. Sounds like you have gas in the oil. Not a good mix.
