    7th pic down the small needle valve is not sealing. You need to remove them and clean them or better yet replace after cleaning inside where it seats with carb cleaner.

    When these don't seat properly it's like the the stop cock in yer bog not stopping the cistern from overfilling. That overfilling goes into your aitbox and down the cylinder. Change your oil!

    don't ride it with petrol contaminated oil - asking for big trouble.

    “And my existence, while grotesque and incomprehensible to you, generates funds to the exchequer. You don't want to acknowledge that as truth because, deep down in places you don't talk about at the Green Party, you want me on that road, you need me on that road. We use words like freedom, enjoyment, sport and community. We use these words as the backbone of a life spent instilling those values in our families and loved ones. You use them as a punch line. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the tax revenue and the very freedom to spend it that I provide, and then questions the manner in which I provide it. I would rather you just said "thank you" and went on your way. Otherwise I suggest you pick up a bus pass and get the ********* ********* off the road”

    If you grew up riding old bikes, turning off the petrol tap was just what you did!
    Vacuum petrol taps changed that a bit but its still a habit I have to this day.

    You pushed up the floats with your fingers until the float needle stopped the petrol coming in, that doesn't mean the float needle is going to the same position when the bowl fills with petrol. Adjust the tang on the float where it connects to the needle so that you're sure the float is going all the way home.

    Float height needs to be correct as the depth of fuel in the float bowl affects the mixture.

    Life ain't always empty.
