I am on my last nerve trying to get my 74 1.8 ltr L Jetronic fuel injected car started. Bypassed the seatbelt interlock to get the starter to work. Hot wired the fuel pump to get it working and still no go.
I am considering a carburetor conversion and see that Redline has a few kits. The dual carbs system has no choke and the single carb with electric choke has some distance from the cylinder heads. Anyone have any success they could share? |

I don't have a dog in the fight.
I had carbs on my 1st 914. Put an incredible number of miles on it without issues related to carbs. Ignition was usually the problem (bad points, wires, etc.). Carbs can be reliable. As others have stated FI really is the better solution . . . no doubt . . . but it comes with cost and complexity. Just look at modern vehicles. They start at -20F with no issue and modern emissions couldn't be met without FI. I'm a mechanical engineer with a background as an electronics technician that did repair down to component level (resistor, capacitors, etc.). The biggest issue I see with the original FI and with issues on this site is wiring. You guys post pictures of wiring that makes me tremble in my boots. Especially the FI & engine harness wiring. This stuff has been exposed to the heat and elements for 50 years! Bad wiring and poor grounds will cause all sorts of intermittent problems that can make you want to slit your throat. Second biggest issues is that these cars are OLD. Many of the sensors are mechanical in nature (MPS, AAR, decel valves, analog Engine Control ECU, etc). Things do wear out. Sure they can often be repaired or jury rigged but that takes time and effort. Lots of effort! I believe that IF you take the time to properly sort out these issues the stock FI will be fine. I intend to put D-jet back on my project. However, personally, if I could come up with the $$, I'd do the system below in a heartbeat. But. . . . you still have to fiddle with calibration, installation, wiring, etc. http://thedubshop.com/dual-throttle-body-f...gnition-type-4/ My personal reason for the above system is that I prefer the look of carbs and that system would at least get the FI into the digital age. |
