Install a 75 micron fuel filter into the fuel line coming from tank. Make sure fuel line to carb (from on/off valve ) is not obstructed. There should be a steady continuous stream.
Loosen or remove fuel cap (as a test) to see if that helps. If runs ok without fuel cap, replace fuel cap,
If fuel cap doesn't help, turn off fuel and remove fuel bowl, turn on fuel. Again there should be a steady flow of fuel. If not, remove float and inlet needle and clear obstruction. Reinstall needle, float and fuel bowl. If still wont run properly, order a chinese replacement carburetor ($15 US delivered) and replace carb. Then drain fuel from tank and fuel bowl end of every season.
Look for an air pocket below the filter screen at the bottom of the fuel tank. Use a flashlight. If there is an air pocket there, that is the problem.
I agree with Rock. LOL...did same with a Honda motor on a generator. Still had problems probably with old fuel but eventually cleared up with new fuel. I would consider draining tank at end of season, running carb dry and putting straight no ethanol fuel with stabile fuel stabilizer in tank. Use the 360 version with a metal tank to minimize rust where fuel doesn’t contact tank.
Hi guys , thank U both so much for yr time and info. I've done all that U mentioned. Just before I go for a new carb , could it possibly b a faulty stop switch at all
Unlikely if it runs at all. It’s fuel.
Hi all, thank U for yr help. Just thought I would let u know ,after stripping the carby and cleaning it twice , I took the advice of buying a new $20 carby and it start first go and cutting the lawn beautifully. Cheers

take the carb bowl off it may have water in it , that will make it not run

I think you may have to connect the governor (wind driven flag connected to the carb that pulls speed down when rotation gets too high, but I don't know without seeing it.

I have a similar Honda (with the overhead valves) that someone gave me because it didn't run at all. Turns out it had a stuck open exhaust valve. I got it unstuck and changed the oil. After running it about an hour, the valve stuck again. I think this is an inherent problem with these engines. I cleaned up the valves really well and lubricated them. Then I put a high quality synthetic (actually motorcycle racing) oil in it and have been running it for a year now with no problems. Not sure what your issue is, but with stuff blowing out of the exhaust and loss of power, I'd pull the valve cover off (prop up the front of the mower and you can do this without losing any oil). Check your valves and give them a good cleaning. They may not be seating properly, which would cause the symptoms you describe. I'm just an amateur, but I'm learning every day! Hope this helps and best of luck to you Lou.

Hi Paul
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.
