    Hope someone hear might of used kegs of beer before
    But I have a keg with S-type coupler and a primary regulator

    Its all plumbed up and i set the pressure right and got the perfect pour. But came back half an hour later and the pour was complete froff. So anyone know why please?

    If you could fill in the following blanks we could help you out with this.
    Regulator pressure?
    Beer line inside diameter?
    Beer line length?
    There is a balance between line size, length, and pressure.
    You need the right pressure for the level of carbonation you want, but you don't want that same pressure at the tap.
    Physics come into play with line length and diameter to reduce the pressure at the tap.
    My personal setup is as follows, which works for most styles of beer that I brew (mainly IPA's)
    Regulator pressure approximately - 12 PSI
    Beer line diameter - 3/16" (approx 5mm), recommend a fairly heavy wall thickness on the tubing)
    Beer line length - 10 feet (3 meters)
    There is a chart for this here on Brewers Friend, not sure where, but someone will direct you to it if you can't find it.

    There is another factor that can cause foaming, that is the temperature of the tap itself, and your glass as well.
    Warming of the beer when pouring will cause foaming, a longer shank inside your keg fridge will help.
    I like to keep glasses in the same fridge that I pour from so that the glass and the beer are roughly the same temperature.

    Hope this helps!

    Couldnt really say more.

    Only other thing is cleanliness, when did you last clean the beer line and tap?

    Is there a chance that the beer in the keg is freezing?

    Is this a new set-up? If you've got a long serving hose you can end up with a foamy first pour. The freezing thing is a good possibility if the hose is close to the cooling coils and is partially obstructed with ice. When you say you set the pressure right, what setting did you use.
    as @Craigerrr says...fill in some blanks and you'll get some good advice on how to fix it.
