Thanks for thr video, i've literally tried everything other than cleaning the carb (full service, new plug, blade, air filter and lastly 99 ron petrol) . I have even fitted a new copycat carb but it also does the surging, so frustrating. My old briggs classic starts first time, everytime and I rarely service the thing!!

Nice fix

[@TurnersWorkshop97]

Cheers mate 😊

Nice video - thanks

[@TurnersWorkshop97]

Thank you, no problem 😊

Great stuff, does the air filter still need to be washed and when dry oiled like on the older mowers ? Many thanks.

[@TurnersWorkshop97]

Yes mate, same as any sponge filter. Clean and then a light coating of oil. Apologies I should have mentioned that 👍🏼😁

[@DARTraderMediaProductions]

When I used to trade in them it was always the case but I've never worked on these plastic carb type. I thought maybe they had done away with it, I guess the plastic is so much cheaper than a metal carb but do they last like the old ones I wonder. Many thanks.@@TurnersWorkshop97

Was that an engine swap or is it apost to look Like that

[@TurnersWorkshop97]

That’s the standard engine for the mower I believe, quite big for a small deck 😂

[@briangibson6527]

I did exactly as you said , Carb' was spotless ,Pipes cleaned and checked, changed old fuel ,then had to put new carb' on as still hunting?? changed plug , changed fuel cap, new filter,primer perfect??? why the hell is it still surging,?? I give up;as I've double checked everything. Help.

Run some torch cleaning tips thru every hole in the carburetor and open up/clean very good the main jet. Should solve your problem, if not I'm here too help

[@shaunsouthern7931]

The pipe with o ring next to pilot jet does it have a hole in, or is it completely closed please

[@TurnersWorkshop97]

They run so lean for efficiency it might be worth opening up the main jet slightly. Failing that a replacement main jet assembly isn’t too expensive.
