Idle jet.

@jakeyboy blocked with what? crap from the tank, are you using a filter? is the tank clean enough inside?

[jakeyboy]

@ringdingding no filter for the fuel, and very hard to tell as the hole is tiny so can’t make it out

[jakeyboy]

@ringdingding and haven’t a clue about the condition of the inside of tank

[jakeyboy]

Would what I’m putting on my air filter have something to do with it?

@jakeyboy Upload some pics dude, it will be easier to see and assist you then!!!

[jakeyboy]

Ok sound, pictures of the inside of the carb I’m guessing? Haha

@jakeyboy Yes if it keeps getting blocked then something is pumping out some crap somewhere? Most likely you either have a blocked fuel filter or no filter at all? You can add an in-line fuel filter for as little as £1. It would be worth adding one of these as they are transparent and then you can see what's being pumped in and if it's good or bad???

Emptied fuel tank, just clean fuel. Cleaned it out also. Cleaned air filter also and still getting blocked... any recommendations? Shall I try size up the jet?

[finnerz89]

Yeah I recommend an inline fuel filter

Have you removed the fuel tap at all? Start with that and flush the tank with water, could be plenty of dirt sticking at the bottom. Just give it a good clean and when you put it back together make sure there isn't any water left at all, that could lead to serious problems. Also check your air-filter, if its slightly oily that is normal. Check the seal is still intact between your filter and airbox outlet, I imagine if there isn't it can let dust and dirt get through which will eventually cause issues.

And as the others said, an in-line fuel filter is almost a must-have. You can buy them in a bundle for next to nothing.
