...or was I suspposed to do it like this: "Valves 3, 7, 11 need to be adjusted when valve 1′s lobe is pointing up. So these four valves can be checked at the same engine rotation. Valves 5, 10, 12 get checked when number 4′s lobe is pointing up. These four can be adjusted. Valve 6 gets adjusted with 2′s lobe pointing up. These two.. Valve 9 gets adjusted with 8 pointing up. These two." Where I THINK Valve 1's lobe is the closest to the front of the car. (correct me if I am wrong.)

Another question, the valve adjustment. When I did the adjustment I measured out the distance between the bottom of the lobes on the camshaft to the top center of the rocker arm not the distance between where the rocker arm presses down on the valve and the top of the valve itself. Is this correct? I could not get a feeler gauge between the rocker arm and the top of the valve.

does anyone know what the timing should be after it advances at higher rpm?

I believe that device you are referring to is the device that interacts with the linkage, and connects to the throttle control valve opener. I am talking about the device that is directly above the front SU carb. This device, I believe is not connected to the throttle linkage in any way. it looks like its connected to the manifold.

For lack of better words: its the round metal canister thing that is above the carb on the left side of the photo.

1973 Datsun 240z S30 Manual Comparison Trouble
Hi, So let me start off by saying I tested the compression and the adjusted the valves, cleaned the carburettors and got the car running fairly nicely. However I am getting little to no power at 3000 rpm+ My guess is that I have the timing set incorrectly and that the vacuum advance (which I had connected when setting the timing) is retarding the timing at idle giving me a false reading. Is this true? I have to go work on it this weekend. I noticed the timing advance goes up by almost 35* + when rpms increase in neutral. Second. I am not, for the life of me able to figure out how this manual downloaded at XenonS30 matches up with my car. The mixture screw is in a different location, the idle adjustment screws are different. I don't think I have the EGR control valve? or atleast dont have the valve in the same location. Here is a picture of the cars engine: I am just having the darndest time adjusting the carbs according to this manual with the different terms they use/different locations. Any help is appreciated. I have been working on this for awhile and have come pretty far from having a car that hasn't started for awhile. Also I was wondering if there was a good stock setting for the mixture screws or do I have to adjust those according to how high the float bowl is before it shuts off according to this source: Technical Information Page ..... Carburation -Eric P.S. Why do I have the domed carbs when the 73's came with the flat top ones that people hated and called "boat anchors"? Lastly, what does the round vacuum device just above the front carb do?
