Right, this evening a friend of mine showed me a odd little trick that has worked! He cut a 2l coke bottle off about 1/16th from the top, cut slits in it ( so it could fold over itself) and put it into the intake where the mushroom filter attaches to the induction pipe (hence the slits), then we just kept cutting more and more of it off until it ran right, fuel cut immediately stopped, but it was running only 0.4 bar, so we cut a little more off each time till its running a steady 0.6 sometimes peaking to 0.7 (not sure why but I'm sure ill dig a little deeper and find out).
