Hi, I need to know if anyone around has a functional, decent (not performance, not perfect) setup that involves a center mounted carburetor on a 1.8 L engine. While I'm new to the subject I'm well aware about the inefficiency of the center mounted single carburetor setup on 914. Yes, it sucks ! But I have to deal with the facts and the reality. This are the facts: I bought my 74 1.8 already converted on single carburetor, (looks like a Weber, made in Spain, no other markings visible without removal) paired with a centrifugal advance distributor (not sure what model, no markings visible without removal) not know when was converted, or if the engine is stock or not. While has a decent acceleration response, decent power it runs very bad, inconsistent warm startup, high idle, rich, overall I can't find a "sweet spot". So far I changed the points, condenser, wires, spark plus, spark wires, distributor cap and rotor. The car is in what I call "active" repair/restoration which means that I have to keep it running and do work on it whenever I have the time and a place to work on it. So far is in my friends shop but while I will continue to have shop access I can not keep it there anymore, so it has to be parked on the street (it is registered and insured). For now I have to keep the car running with a single carburetor, so any other option is out.
Now... not sure if the centrifugal distributor is a good idea for this already bad setup, but I need opinion and advice from people who know how to do a proper setup for a single carb. I will add more info and photos over the next days Thank You ! PS. It looks like I have a 1.7 L not 1.8.The engine serial nr starts with EA, assigned to a 1973 1.7 L. Attached thumbnail(s) |

You may find people that have gotten single carbs to run, but you wont find many that have gotten them to run well. The problems you have stated are very very common with single carb set ups. they just don't work all that well becasue the fuel start to fall out of suspension before it hits the intake valve.
T1 engines got around this by running exhaust gasses up along the intake runners from the single carb to keep them warm and keep the fuel in suspension that way. 914s can't do that. Well, not easily. Spend a little bit of money to get a dual carb setup, and you will be very happy that you did. Your car will run much better, and you will get more power out of your 1.7. Zach |
