Rough Idle bosch

[Jenkosowls]

Done the bosch conversion otherday and im having trouble finding a happy medium with max fuel, idle when hot and cold. At the moment im only hitting around 18 psi but cant properly set up the idle.

When i start the car from cold (no wax stat cable) it will stutter and be rough. once warm it will idle above 1k even though iv go the hot idle wound all the way back. everytime i turn the engine off and start it back up wether its straight away or 15mins later it will stutter and idle rough at 500rpm to the point it nearly cuts out. it will also do this when turning the car full circle or putting any load on. But give it a quick blip on the throttle it will idle again above 1k.

How can i go about putting the wax stat cable back in? wait for the engine to be stone cold and moving the cold idle all the way to the left and attach the cable?

Any info would be great thanks
