I'm not sure which sound you are talking about. One I can hear is noisy belts. Another sound I think I can hear is where you open the throttle VERY QUICKLY and you get a CHOOF sound upon opening it. If you hold the throttle open does the sound keep going? Really doubt its your turbo.

Sounds like a big leak to me, or loose belt, but gas leak more like, see if there's any black burn/carbon marks coming out where manifold bolts to head. Just sounds like it (reciprocates) every engine fire/ second rotation

Thanks for the reply I know the belts are the next thing to be changed I guess I'll have to check out all the bolts

As for the turbo yes iv

Driven it around when I did it and a day after I also did put a stainless steel front pipe so I think that might be it?!

    • Based off what you鈥檝e said here, I think I鈥檝e figured out a good bit of what I鈥檝e done wrong -  So on the line going from the PCV valve to carbon canister, there鈥檚 a T joint that is pretty much right next to that lower port - I hadn鈥檛 noticed that the hose in the diagram was curved to attach onto the carb, so I was putting that line for the lower port onto the PCV line / carbon canister line instead. I鈥檓 going to have a flick through the manual again tomorrow and should hopefully find a diagram that鈥檒l show me where that T joint should be connected to. Timing also 100% needs to be sorted out as well, should be able to tackle that tomorrow as well. Definitely feel like I should be on the right track now though. 
    • The screw is for idle (pilot circuit) mixture adjustment. Else, I'm confused ~ the diagram shows 2 carby ports, and the intake manifold port, but you're suggesting the "2nd port on the back of the carb that isn鈥檛 mentioned in the diagrams" ...yet, both carby ports are shown...que?... ...in any event, that port should be connected, but if not (like it is now), it's unlikely to cause a backfire out the carby (it would introduce false air and give you a fast/lean idle) ...sounds more like timing issues/spark plug wire routing responsible for the backfiring.    
    • That's fair, I can see both points. I get enthusiastic when I see the FS section has a new post and want to see what interesting thing someone is selling. Then I get deflated it's a bump of a 10 year old post. Ha ha
