Hi Mick.

Couldn't upload pics of the Briggs in struggling with so I've messaged on insta if you can reply that'll be great.

Also cleaned out carb but still hunts... proper carb too not a plastic one. Any tips appreciated as always.
Cheers.

Greg, I don't see the pics on Insta either.  So what machine / engine, and what issues are you having?

Please check mick as I sent three pics. Engine won't turn off.

Mick

Greg, I edited your first post to add those images.

Hunting, either a gummed up carb, Really bad float level, or split inlet tube.

And as you mentioned it won't switch off.  Looks like all is ok there, unless the control plate isn't touching the switch contact.  Make sure it does touch it when in the off position.

If that's ok then you either have the stop wire disconnected from the coil, or a broken wire (Rare), or a faulty coil.

EDIT  Looking at the stop switch it looks like the wire is fitted incorrectly.  You need to push that metal piece the wire is hooked through now, and then poke the wire through the hole below it.

Cheers mick. Will have a look.
I didn't notice the black plastic plate that goes between carb and engine wasn't on correctly. Could that affect its running? Thought car was cleaned as all jets seemed clear.
Also the second screw on the carb bowl. Should that locate on the little lug that sticks out on the "shaft"?

Yes if it's letting air in then it will cause issues.

Not got a pic at the moment Mick. There's a screw that's attached to the bowl from an angle. Like on some gcv Honda engines. Not sure what they do.

Mick

Greg, do you mean the bowl drain bolt?  That's all I can think of, as some have them and some don't.  It's just a drain.
