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. (IMG:style_emoticons/default/sunglasses.gif) |

Whole I agree on getting rid of the single, it still should do a bit better than that.
Sounds like a number of things were changed so you just have to start working through the list. Try the following and drive after each step to note any changes. 1 Timing. I can only say this because I have done it. Make sure that you don't use the 27 mark on the 2.0 impeller as TDC. It makes your car run very poorly. 2. Verify your fuel pressure is not over 3.5 lbs. 3. Clean out all of your fuel filters and verify the float level is set correctly. 4. Blow out your idle and main jets with air. 5. Set valves 6. Check compression. |
