TL;DR: I inherited a honey-do that is a 914 and looking to get it running. Currently seems to crank slow and has sat for a while with little/no fuel. Update: The #1 cylinder appears to have dropped a valve. Teardown commences.
My name is Sean and my Fiancée inherited a 1971 Porsche 914 from her father. It has sat for many years with little (maybe no) use. Therefore, I’m looking to get it rehabilitated and ready for some pictures this spring and our wedding this summer. So, I may reach out with some questions here and there. I’ve utilized this forum and many others for a crash course which have proved to be invaluable. Even if some of the posts now exclude originally attached pictures or were before image storage was readily viable. The car appears to have been obtained through a Haggerty auction/dealer. The car came with a good amount of spare parts (including what appears to be the full FI system maybe sans wiring harness). To an untrained eye It looks to be in excellent condition, with the exception that it only ‘ran’ prior to being dropped off. I have yet to get it to run myself and am currently going through rehabilitating the fuel system but it also seems to crank slow. I didn’t realize that not only was I fighting old fuel but no fuel. I should have taken pictures prior to some disassembly so you could see the car but maybe y’all and I can revel in some completion photos together. What I know about the car: • • Targa • Fuchs Wheels • Weber IDF 40s • *some exhaust system* • Clifford security system (super afraid of the wiring on this) • More to be discovered? Work in Progress: • Removal and cleaning of fuel system o Clean tank o Replace fuel strainer o Replace lines (including tunnel line which happened to be copper replacements on both) o Replace fuel pump and filter o Addition of fuel pressure gauge inline gauge This may be temporary if the FPR is accurate and consistent o Rebuild/refresh carburetors (new task to me; pointers welcome) o Run new wires for oil pressure and temp gauges At this point I’m open to any and all comments/suggestions. Especially advice of things to do while certain areas are opened up. I grew up on Nissans and have a ~380HP Nissan 240SX (Silvia) as a fun car. So, I’m excited to see this car come to life as one of the first Porsches and air-cooled cars I’ve maintained. https://photos.app.goo.gl/n8L1BejZ0xrDZmdQ2 https://photos.app.goo.gl/s5irKrca1vDfuSV37 What is the spade connector for in the middle of this picture resting on the block? Appears to be off of the ignition harness and is not shielded from shorting/grounding. |

Alright, so after a vacation and a short break. I've got the Tangerine fuel line and Facet fuel pump installed and wired. I bought two Redline carburetor refresh kits and removed the LH carburetor and got it all cleaned up. There was some green sludge in a few of the parts. However, the main galleys/body of the carb. were clean.
I've never done any work on a carburetor before nor really been around carb. cars. So, I wanted to pick some veterans' brains for tips/tricks. I diagrammed and counted the number of turns, as best as possible, when backing out all screws. Also, please check the second picture in the first post as I meant to post a picture of some engine harness wiring and not the torn apart interior! What is that white quick connect connector in the middle? Quick questions: What should I do about the enrichment/choke mechanism on the inboard side? I've seen some people block them off with plates but obviously this car ran fine with the mechanism on but nothing attached (closed). Probably just ignorant to how leak proof the internal valves are. The little spring loaded part on the top side of each were stuck but a light push got them "springing". I have a new float spring/damper but was curious if I should bother replacing it. Any tips or tricks are greatly appreciated.

I pulled the intake runners to clean and replace the gaskets. When I did I saw a small chunk in the intake port, small pebble(1/8" at best). Thought it may have been on top of the runner and fell in. Decided there might have been more that fell in and figured I'd vacuum out the port and found this: https://photos.app.goo.gl/XaRxfKkyqj5LbAzFA/ Also, this was in the runner itself: https://photos.app.goo.gl/ctpQ4R4nhrYXQwt39 Damn....I had heard my father-in-law struggled to get it running before it made the voyage here but when he did gave it hell. I think he melted a piston and/or made valve-piston contact with a hot engine occurred. Likely got too lean and melted something. Time to drop the engine, disassemble, inspect, and rebuild. I would start to pull the trigger on rebuild parts but I have no idea what may lay underneath (bored over, etc.) So much for spring/wedding photos. Haha. Here we go, trial by fire in 914World. (IMG:style_emoticons/default/drunk.gif) Any and all tips/advice welcome. I just bought a Quickjack to facilitate some (not an engine rebuild) of this work. Any ideas of whether or not it will get high enough to clear the engine when dropped? |
