To complicate matters,the black rubber fittings are entirely different .the method of actuating the various vacuum functions are different ,so is the throttle body.
The Warm up regulator ( that device to the right of the airslide ) is also different to the electronic airslide.
If the airslide is the only thing to have been changed ,you are in luck...almost.
I am beginning to think your hot start problems are tied to this bodge with the warm up regulator not being connected properly.
I have just had a quick look at one in the shop I am tuning and it has also been bodged exactly the same way. The control box for the idle is still in it's correct place though.
