No Torque from 33 1.7 IE (inject)
Yesterday I brought home a '89 Alfa 33, I was intending in using in some club events, starting with a Khanacross - Rally speak for driving on the dirt for a run, though flags, loosing 5 sec's for each one you hit.
This is my 7th Alfa, previous one's have been sud's, and 33's. But it has been ten years since having my last. So I'm a bit rusty, and definitely unsure about the fuel injected of this car (all my other's have been Carb's).
So I have this car, which smell's very rich, and has no low rev's power/torque. I have checked the air filter, replaced the spark plugs, checked the disti' cap and rotor, cleaned them up, and have also, adjusted a white screw on the bosch box, that sits between the air box, and manifold. - I am hoping this is the air mixture screw. I found a reference if I turned this screw counter-clockwise, actually I turned it 12 full turns - counterclockwise.
The exhaust does not smell as rich, and I can now reverse out of the sloped driveway, but it is still not right. It has trouble climbing a hill.
The bosch box has jetronic on it, but not much else.
There does not seem to be much to adjust (that I can see).
I am looking for suggestions of what I can do....
