Alright everyone, I need a little help.

I have a '73 914 with a 2.0. Spent the last 7 months rebuilding the brakes, suspension, interior and painting it. PO said the engine was recently rebuilt. I haven't checked the compression yet. It has a single carb, Weber/Redline 32/36 DGEV recently rebuilt. I didn't record the jet sizes. My problem is that it just doesn't pull hard at all. Took me almost a mile to get to 45mph and 4th. At rest, when I work the throttle, it responds great and spins up to high RPM quickly. I verified that the accelerator is opening the throttle all the way. I have verified that I don't have a break/caliper that is stuck.

Not sure if it is related, but just to have the whole story, it also has issues starting. With a newly rebuilt starter, new fully charged battery and with all the ground straps removed, cleaned and tightened. It turns over for a second and then just stops, hesitates and then turns over again but very slowly. Key off/on and it does the same thing.


I know the aerodynamics are not that bad! (IMG:style_emoticons/default/evilgrin.gif) So where do I look first and then second?

Thanks.

For some reason that drawing strikes me as wrong. Let me check on some things before you change.

The drawing is right. I have been putting the wires on 914s like that for over 25 years.

I would float test that carb. Throw it in a lake, and see if it floats. If it does, use it on the car.

Check the distributor and see what model it is. Some distributors, like the infamous 009 should be float tested with the carburetor. If you do have a 009, you will get some lousy performance because the advance curve is completely wrong for the engine.
