i know this is a very heated debate. with many supporters on both sides. (It seams a few more for FI though)
here is my situation i have a 73' 2.0 (scored a great motor with 26k original miles in my parts car). i currently am running the stock fi from the 2.0 and am having so many problems i am having to consider carbs (like a set of Webber 40's)
I'm no seasoned Porsche or vw mechanic but i know my way around a tool box.
I like the idea of keeping the stock fi (if it is practical to do so) but i cant see spending what it would cost for a 6 conversion just to make the stock fi work properly. the carbs seam a bit less complex, more straight forward tuning. Also i am not wanting to go as far performance wise as a more aggressive cam or anything, stock hp would be fine though more is always welcome i just want something i can get in and drive anywhere (sometimes just a little more quickly than others
)
1) the car doesn't like to start easily, but that's understandable with a non functioning fi
2) on idle it runs rich!!! so rich in fact that my idle screw operates in reverse turning it counterclockwise will result in a higher idle this i have to assume is my mps (looked around but I'm pretty sure these are NLA)
3) power is minimal to say the least, it will go 55-60 just not as easily as it should
i have the enrichment knob on the computer turned completely lean and still not functioning properly all lines are new both fuel and air and connected correctly (thanks pelican for the diagram) fuel psi was 29 and from what i can gather that's perfect, i tried turning it down but still the problem persists
my valves are adjusted perfectly, timing is spot on, tune up is brand new, wires,plugs, rotor cap and button,i have electrical ignition in place of the points all hidden under the distributor, i even tried 5 gallons of 110 octane fuel and nothing
temp sensor II is brand new and tested as working in range, thermo-switch is functioning properly
if anyone wants to give me a helping hand with my fi please do, and if not let me know why carbs are the way to go. now there are a few questions about the carbs id love to have answerd
what can i expect MPG wise from dual 40's i really dont want a 4 cylinder getting 10 mpg
are they worth the cost vs fixing original fi (i think i can get a new set for around the $700 range, i would also need a new fuel pump)
also will throttle response be a problem with the carbs i wouldn't imaging so but i thought i would ask
Thank you all more than you can imagine, George
If only my enthusiasm where replaced by knowledge
