  1. SOLD! A pair of seats from a '73 BMW 2002. The upholstery is completely shot, but the seats are basically sound and are complete with headrests etc.. I'll add photos if there is any interest. Pick up only in Pasadena, CA - these are too bulky to ship :-)
  2. It's exempt from smog in CA, but think of the children! The car is on Ebay - not sure if I'm allowed to post the link here, but it's not hard to find. Julian
  3. It is a Weber :-) I do seem to have all the jets that are in the Weber diagrams I've seen.
  4. The thing smokes so much I'm reluctant to take it on the public roads: it's a bit of a Catch-22! I'm not sure anymore that it's a carb problem in any case - everything on the carb seems to check out. (The power valve is working correctly.) On the other hand, six months ago, before I started messing with the carb in an attempt to fix a rough idle, there was no smoke/rich running issue. Thanks for all the suggestions - much appreciated. If anyone reading this lives nearby and would be kind enough to take a look, please contact me.
  5. I'm in East Pasadena, and would be delighted if anyone nearby has the time to take a look - I offer a 6-pack or bottle of vino :-) There's a shop up on Colorado Blvd. that often has older BMW, Mercs and Porsche, so I may wander in there to see if the mechanic will take a look.
  6. I've about had it trying to fix my rich running / smoking exhaust problem. I can't see what is wrong - everything looks fine, but it's just so frustrating to keep firing the thing up after the latest fiddling around, only to have it warm up and start belching smoke again. I've been weeks off and on messing around with the Weber, the timing, plugs, wires, dizzy, ignition etc.. It started out fun, but now it's gone sour Any bright ideas? Anyone with a known good Solex they want to dispose of? Or should I just put the car up on Ebay and call it a wash?
  7. I wasn't sucking hard enough! When I suck really hard, the piston moves down, and moves back up when I stop sucking. Here's another thing I don't understand: if I keep screwing the mixture screw in (clockwise), while keeping the revs up a little to keep the engine from stalling (it will stall otherwise), there is no noticeable reduction in the smoke coming out of the exhaust. I would have expected that leaning the mixture would have stopped the smoke, no? I have something really screwed up somewhere, I'm sure!
  8. I'm sucking on the hole circled in yellow (attached image), but the piston/spring isn't moving. The air passage itself is clear as I blew it out with compressed air both ways after removing the three screws and the piston. What do you think?
  9. I'll do these tests and report back. While I have the cover off I'll try bending the tab to decrease the level (i.e. increase from 41mm at shut), right? Great suggestions - thanks!
  10. I've checked the brass floats carefully - they are undamaged and do not take on gas. They are both sitting at the same height. With the cover vertical, the floats hanging down, and the tab just touching the ball bearing, I measured 41mm from the cover gasket to the base of both floats. With the cover horizontal, and the floats hanging down, the measurement was 51mm. So, as per specs. The valve itself is new - the tip is clean and unscored. (It has some reddish paint on it, which is unmarked.) If I look in the float bowl after the engine has been running a while, and after I remove the cover, I see maybe 15mm depth of gas. This doesn't look like a too-full amount (?). I feel I'm missing something significant. My main idle jet is a 50 - perhaps this is too big?
  11. Thanks for the encouragement - that's two votes for throwing it in the bin, and one against I have read most of c.d.iesel's posts on this topic, but my problem remains. I don't think my problem is main jets, but I may be wrong. I did try the 60/55 idle combination already.
  12. Background: this is a '73 with the original engine, pertronix points and a Weber 32/36 with water choke. The car hasn't been driven regularly for some years, but everything "works" - I've been mainly doing r&r on things like new plugs, wires, oil, filters, seals, setting timing, etc.. Now I am ready to go out on the road, but have a couple of issues before I do so. The main issue is I seem to be running very rich - there is grey smoke out of the exhaust once the engine starts to warm up, and the plugs are sooty. I'd like to put some miles on the engine before getting too hung up on tuning etc., but the state it's in is producing too much smoke to drive without a gas mask My feeling is that the carb is set up incorrectly. Here's what I have: 1) brass floats: level set to 41mm when valve closed, measured from gasket to extremity of both floats, level set to 51mm when floats at bottom of travel 2) idle jets: 50 on primary, 55 on secondary (I also tried 60 on primary, but that was predictably worse) 3) main jets: 125 on primary, 127 on secondary 4) correction jets: 175 and 170 5) emulsion: both F50 6) discharge: 50 I start with the idle mixture screw 1 1/2 turns out from fully closed - the engine starts (but without enthusiasm). Turning clockwise (leaner) the engine starts to stumble. Engine seems happiest when the screw is about 2 turns out - which is apparently OK according to what I've read. Vacuum on the manifold is 20mmHg at idle. I'm pretty confident I have no vacuum leaks. Air filter is removed for these tests. Observation: before the engine warms up, if I open the choke butterflys by hand, revs go up. This suggest that I'm running too rich, doesn't it? After the engine warms up, butterflys open completely, as they should. By the time the engine is warmed up, the guff from the exhaust is choking! Any comments/suggestions? Any local experts in Pasadena who'd be prepared to take a look? I feel like I may be missing something basic related or unrelated to the carb!
  13. Hi Roland and Daron, I realised based on the feedback that I really need to drive the car a bit before pursuing this any further - it may just be that it needs a good run To that end I had to replace a couple of the tires, which I did this week. I also got hold of 55 and 60 idle jets from Ken and installed them, and re-timed the engine after my repair of the distributor. Now I'm all set for a spin round the block, and perhaps further, but some dude has parked in front of my gate, and I can't get the car out! I'll report back when I have more news
  14. Cool - I ordered a bottle - thanks!
