The other item which is key to the results are the chokes. What size are they ?
For a standard engine, you should not be running any bigger than 32mm.
The 45's are really too big for your application, you should be running 40DCOE's on a standard engine. You will find it almost impossible to find 32mm chokes for 45's, I've only ever seen one set in 10 years, whereas 32mm are standard on 1750 & 2000 euro engines.
The 40 DCOE's are good for up to 165 / 170 bhp, and can be choked up to 36mm.
To give you an idea, my last GTA Rep ran 40 DCOE's on 34mm chokes on a two litre with extensive cylinder head mods, and much better camshafts, and gave 165 bhp.
I ran it on 45 Dellorto's to start with on 36mm chokes, but it was far more drivable on 40's and smaller chokes.
As others have said above, the jetting is way out too.
If I were you, I'd sell the 45 DCOE 152's and buy a pair of 40 DCOE 151's, much more suitable for your car, unless you're imminently considering modifying the engine radically, with extensive porting, higher compression, maybe bigger inlet valves, performance cams etc.
You could offer to swap with cash your way for a pair of 151's, as 45's are more valuable than 40's, provided they are in a similar condition.
