    I interpreted the graph to show 15 crank degrees at 1500 crank rpm. At 3000 crank rpm, the spec shows about 34 deg, before maxing out at about 38deg at 3500 crank rpm. I've read that these M10 engines are best kept to less than 40deg total advance. I cannot explain the setting shown in the manual. Setting to the specs shown in the manual -- 25deg at 14/1500 -- would imply about 10deg of static advance and 48deg of total advance. Are you sure the spec in the manual is with the hoses disconnected and plugged? Or, could it be with the hoses connected? Is it possible that the CA variants of the above distributor had some form of advance limiter, which limited the curve at the top end to keep the total advance below 40deg? One way I've seen it done (on Magneti Marelli distributors) is where one of the 2 advance springs are replaced by a metal loop which limits the max advance. What is the spec on the emission sticker in the engine bay? Byas

    The rpm on this graph is for distributor shaft rpm which is 1/2 of crankshaft rpm. So multiply by 2 to get engine rpm and you'll see that the curve starts at around 7-800 engine rpm. Also, multiply the deg -- the curve is in distributor degrees vs. crank degrees. So, proper setting for you car would be about 15deg at 1500 rpm with vacuum hoses plugged. You have it set with more advance than the spec.

    And, Tii header and non-Tii header without the emission stuff (early) are functionally the same - if you want to go a less expensive route.

    Nope, at idle, the timiing mark on the pulley may not line up -- the spec is about 2 to 7 deg at idle, so it should not.

    Being more specific would help -- what have you tried and what exact difficulty are you running into? Is the bumper all in one piece or is it disassembled? etc.

    At partial throttle it should be lean. Look at the 5000rpm curve on this graph. At idle (no load) it is rich, and gets rich again at WOT, but leans out at partial throttle.

    Good point. I used it for setting idle CO% (as the specs called for that). But, didn't consider the oxygenated fuel impact.

    You should not expect to see one AFR all the time. At partial throttles it should go leaner. See these curves for AFR vs. throttle position (air consumption varies with throttle position) at constant RPM. Byas

    Amazon says mine should be delivered today.

    If you have an air bubble trapped under the closed thermostat, I think you can have the same result. At least that was the case in my 80 Fiat Spider which had a similar setup. Drilling a small hole in the thermostat allows that trapped air to get out.

    Wheel chock location on '74.

    As I mentioned above - vin plate matches. I had already sent a note to Andreas. Will see if can shed any light. Byas

    Vin plate And engine number match the active body vin.

    I wanted to talk to the owner, but he was not around at the time. Wonder if he is on this FAQ? B

    Brisbane S&S entry - $20 Bunch of hard to find Tii parts - $170 Getting to know your fellow enthusiast and their cars - priceless And my parts score: Clean powdercoated rear trailing arms (unused since powder coating) NOS Tii battery tray and hold down Wire set with suppessor and test socket NOS suppressor Tii water pump Clamps and some tools Byas PS: Rob -- did I win those boards?

    I've never seen this before? Surely not factory? Byas
  18. bnam
    I did that on my 74Tii. I don't remember what I used though. Don't recall anything special. Byas

    In your third pic, there's a flat spot on the engine casting to the right of the starter (between the strter and flywheel). The flat spot is horizontal. The engine number is punched there. May need to clean a bit to see it. Byas

    Depending on where you are -- try to go to an '02 event and see a lot of cars and talk to their owners. Brisbane this weekend in Nor Cal, theres the Vintage as well (not sure of exact date) Byas

    Looks good. B
  22. bnam
    That one's much nicer - at least in looks. Lots of $ spent on both.

    My rough measurements on the the larger hole is that it is approx 19/64" (7.5mm). Will see what I can find.
  24. bnam
    I can get there.

    Tacking on the e30 grill and lights was a horrible idea -- makes the '02 look even more boxy.
