Hey folks. I just rebuilt the weber IDF 44 carbs on my 914-2.0 because I was experiencing hiccups/stutters in acceleration from idle to about 3k rpm. Also, the car would idle very low, and then die if you did not give it a good amount of revs after starting. I figured my idle jets were clogged, and since the carbs had not EVER been rebuilt, I re-gasketed, and rejetted them.
Just finished that today, put in new fuel line to the carbs, changed the fuel filter, and troubleshot a strange problem where my accelerator cable seemed to wrap its way around the clutch cable and bind. :headbanger After all of that.....my car is STILL acting very strange; in some ways things are better, and in some, things are worse! NOW: The car seems to idle just fine at a very nice 900rpm after adjusting the idle and throttle body.----SWEET! The accelerator cable seems to stick slightly, also, the ball joint for my accelerator pedal seems to keep popping off of the pivot point (Is there a trick to this, or is the ball joint just shot?!) Seem to have it on there now, but now guarantees! ---LESS SWEET Still seems to stutter when reving in gear b/w idle and 2.5k rpm...same as before I rejetted and cleaned (IMG:style_emoticons/default/dry.gif) Shudders and looses power at 4k rpm in every gear...this thing had crazy power after 4k before I messed with anything. (IMG:style_emoticons/default/mad.gif) When I replaced the float needles and seats that came with the rebuild kit, I noticed the seats were way smaller on the rebuild. I DID NOT adjust the float level....my first culprit for this less than stellar performance. After reading some posts on here, it sounds like the float should be at between 12.5mm and 13mm from the upper face of the carb. Would this solve these problems? Also, I DID remove the throttle valves for a clean and inspection when rebuilding...I am hoping this is not the root of the problem, as they do not seem as smooth as they once were. Don't think its the resize in jets, as I just changed idles from .45 to .55, and air corrections from 200 to 190 as per recommendation. Where should I start here!!!????? I figure I will measure and adjust the float tomorrow, after I remove the carbs again (damnit). But if that doesn't work...what should I be trying?.....Damn weber book didn't get here in time and I am not the most patient..... |

So, in order to sync the carbs, I need to get a synchrometer. When this arrives will be the next time I take out the carbs to address the float level any other problems before reattaching them and properly synching.
In the mean time, I want to figure out what these other problems could be potentially.... [/quote]ThePaintedMan Posted Nov 11 2013, 05:48 AM You mentioned that you removed the butterflies, correct? Did you remove the throttle shafts? Also, do you notice any binding, and are the butterflies closing completely on both barrels? You can check this by shining a light down them and looking from the other side to see light (when the carbs are off the car and drained of course).\ My friend recomended we not touch the throttle valves, and of course I insisted we take them out and clean them. Did not remove the shaft, but the way the throttle valves went on , they had a lot of play in how they sat on the shaft. [quote]rhodyguy Posted Nov 11 2013, 06:52 AM confirm the throttle plates are installed with the degree number, like 5*, visible from the top and the beveled edges are in the correct orientation. after re-jetting you got started with going to the pre-install setup procedure, yes? Just for clarification. the numerical stamp on the butterfly valves should be facing into the engine? or upward into the top of the carb? The LAST thing I want to do is score the inside wall of the carbs....BTW, after putting almost 15 hours of work into this project, patience is something that wears thin.... but I will always have patients for this car..... she's my baby. wndsnd AhA! C-Clip ordered, temp fix safety wire! Thank you all for your input. Will let you know if I have any more questions. |
