    Thanks. Is it permanently fixed to the cable or can a used one be fitted seperately? I see the same part number is listed for the E12 series as well.

    Are these fitted to all tii's? Here is a photo of the setup on my '74tii which shows a single piece enrichment lever with no place for a return spring: This is a photo taken from jgerock's post on this forum showing a two piece lever with the return spring. Am I missing something, or are there variations on the setup over the years?

    Hi Looking for one of these please - Right hand side. Any help will be appreciated.

    OK, so not as easy as I thought. I've got the mixture sorted at idle. It runs between 6% and 7% at 3,500-4,000rpm though. Do I adjust using the washer nut on the warm up transmitter, or the "verboten" adjusting screw as per the Mcartney Book? Either way do I readjust the gap to 2.6mm at the end of the process?

    Am idling a bit high as I didn't have a CO meter with me last night to set the mixture. Will sort this out tonight and set the idling at the same time. The book says 850-950rpm for idle, 1,100rpm sounds a little fast?

    It's amazing how easy it actually is when you know what you are doing!! Thank you all for your advice, and yes it was the ignition and not the pump settings. I replaced the points as the set that I had were faulty, set the dwell angle to about 60deg, and the timing as advised at 2,500 rpm. Hey presto, she is running quite beautifully. There is a bit of pre-ignition (run on) when I switch her off though, so I might need to back off on the timing a little. I still need to check the CO readings, but this should be a cinch now. I had also sprayed quite a bit of penetrating oil on the cone of the warm up valve, and it is now opening the full 10mm. Luckily I didn't even need to take it off. THANKS AGAIN GUYS! Tomorrow I road test.

    OK, so I've checked my cone and it is virtually flush when cold, so I guess it's sticking more than out of adjustment. Is relatively simple to strip, clean and reassemble this unit? The BMW manual says not to try. @c.d.iesel - lol, I haven't been ignoring your advice. The motor is newly built, rebored with NEW 89.5mm pistons and rings, so I'm pretty sure the compression is good and equal (raised to 10.0:1 from the std Euro 9.5:1). The car is newly restored, so all the fuel lines, filter etc are new and the gas tank was cleaned and new fuel added to a dry tank. I haven't checked the fuel presssure, but I checked the return flow to the gastank, and 1L of gas is pumped back in 30sec which falls into the 0.8-1L that I have read in the manual. The timing was set statically - the points just about to open with piston #1 at TDC on the firing stroke. I don't have an adjustable timing light, so any advice on how to set the timing at 2,500rpm will be appreciated.

    Thanks guys, this has been quite helpful. I will try the ajustment over the weekend and see if it makes a difference. I haven't checked to see if the cone is flush or recessed when cold. With regards to the ignition, the points, condensor, plugs, plug leads and coil are new. I went back to points as my pertronix ignitor is faulty. I'm still running the 40,000 Flame Thrower coil though and have disconnected the external ballast resistor as I have the required 3ohms across the coil. Could this be the problem?

    Hi Guys After warming up, the cone on the top of my warm up valve only extends by about 7.5-8mm. All the references I have come across state that it should lift to 10mm. Is this adjustable or do I have to just replace the unit? The car hasn't run for 10 years, so I was hoping that it was just stuck and would work loose. The problem is that I can't set her up to run properly with it like this. The idle is OK and the CO mixture is correct at just over 2% at idle. I can't get her to rev up nicely though and she breaks down at about 3,500rpm. The CO is a bit lean at this point and she backfires slightly on the overrun. Any advice will be greatly appreciated. Thanks in advance

    The problem is across the range and manifests in an idle that hunts between 900 and 1,200rpm, as well as popping and backfiring higher up the rev range. The CO2 readings are about 2.5% at idle and just short of 4% at 3,000 to 4,000rpm. This tells me it's running lean. I have synchronised the linkage from the pump to the throttle body and seem to be struggling with the mixture settings between the enrichment lever on the warm up transmitter, and the air mixture setting in the throttle body. The ignition timing is et at TDC with the points just about to open. I'm still using points and condensor as my Pertronix Ignitor turned out to be faulty. The coil is a 40,000v Flame Thrower unit that came with the Pertronix module. Engine is newly rebored to 89.5mm with std tii pistons (new). Compression ratio increased to 10:1 and 39mm exhaust valves fitted. I'm running an Alpina 300deg cam from Jaymic in the UK. In the Manual I have just downloaded off this site, I see it tells you how to set the air mixture in the Throttle Body which the other manuals neglect to do. It also states not to adjust the screw on the enrichment lever as this is factory set. The Mike McCartney book that I was relying on recommends using this. I'm going to work through the manual tonight and recheck all of the settings again, but the adjustment screw on the enrichment lever worries me now. Any advice?

    Hi I am in SA and have just finished a 10 year restoration project on a '74 tii. It is a RHD Eurospec Model 73 car and I am the second owner. I did a complete nut and bolt on the car and built it to Alpina A4 spec with most of the correct goodies. The car is 95% complete and I trailered it to her first show 10 days ago. This is what she looked like at the show: The reason I trailered her is that I am struggling to set up the injection system. I have followed the Haynes, BMW and Jaymic methods and still can't get it right. I have just downloaded the manual of this site from BMW North America and will give it another bash before I seek help. I bought an "Alpina A4" Kugelfischer pump off eBay some time ago and hope that this is not the issue. I'm getting it close though, so I am pretty sure it is the CO2 mixture setting that is teasing me. Anyway, hopefully joining this forum will be the start of the end of my problems.
