Basically another thing thats gone to s**t for environmental reasons
It doesn’t vary too much here, you hear of the odd bad batch but it’s often down to tank cleaning. One year I had the same petrol in a mower and Aldi whacker, in spring the mower started but ran crap, the whacker wouldn’t start until I drained it. That was approx. 4 months from filling the can at the pump to post-Christmas issues.I think that's a difficult question to answer because it assumes all "petrol" is the same thing.
The petrol I buy in Oz seems to last years without causing problems in "normal performance" engines except for a (now long discontinued) fuel sold be Shell called "Ultimate". This one caused a lot of plug fouling in bikes and was considered to have a shelf life measured in weeks.
The petrol I buy in SEAsia smells strongly of toluene (paint thinners). Apart from being very bad for your health, it acts as an octane booster, meaning it'll compensate for other short comings.

I'd guess your needle valve is gummed up and possibly the main jet .. complete strip and soaking in carb cleanerNew plug again out of the 2 pack got it to run on brake cleaner. Fuel drained and went bought some new fuel. Got it running. Doesn't like revving right up when choke off seems to prefer half choke. Is this hose hanging down on your wackers or have I pulled it loose from somewhere? Im getting a constant drip of fuel when the fuel is turned on. Less if the engine is running but steady drip if engine not using the fuel View attachment 79979

Crazy its a plastic 5l fuel can. You'd look at the state of that and think the machine has been thru the wars. It's just sat for ages prob been used for 50hrs from new. The actual fuel tank on it is quote clean not all crap in it like that.think you need a new fuel can Jim
that's a hell of a mess
that needle/float valve is going to be in the same state ..
little pipe may well be an overflow and the needles not seating properly, flooding the float chamber, 'cos the needle's not seating properly and closing the flow of fuel - pull the float and needle and give the seat a good blast with cleaner and some air pressure after
main jet body is covered in lacquer so is a fair bet everything else is too
Me neither, quicker to stick a new carb on there.Not sure I'm upto the technical ability of stripping and cleaning jets.![]()
really isn't rocket science Jim ... you'll wonder what all the fuss was about once you've done oneThat's a good shout about burning the fuel off rather than turning off. My 2 stroke stuff I always empty the tank then let them run dry. I wonder why this blocks up so easy when the old genny just keeps going. The genny has a Honda gx140 I've ordered a new air filter for it as it was embarrassing when I took the cover off how bad it was. Hondas must be the hilux equivalent of generators do the taliban use them

Good shout. Comes with filter too. Will just have to weigh up whats quicker or easier for me to do. Might have a quick go at the jets nothing to lose.Me neither, quicker to stick a new carb on there.
Non genuine ones sometimes only 20 quid
