It has been over 30 years since I worked on a Z points distributor and I need the forum's help to see if I remember this correctly. I want to change the points on my stock '72 Z. Is it correct to be able to unbolt the distributor from the block, take it out, put in new points and condenser, set the points and put the distributor back in without losing timing? I think the shaft is keyed so that it can only go back in one way. Thanks, Charlie

Thanks for all the suggestions. What I found was this. One, the wheel needed adjusting 1/2 turn clockwise to lean the jet and the suggestion to check the choke cable turned out to be spot on. The cable on the front carb needed to be adjusted because it was not pushing the linkage all the way down. I adjusted these two items and now, after several hundred miles, the plugs are showing a light grey color and all the black soot and sludge is gone. Thanks so much for your help. I am enjoying the car very much and now need to get some grey film on the back hatch to keep the heat at bay. Charlie

I'll check the jets and float levels this week. I have to get out in the early morning as we are having a heat wave right now. Thanks for the replies! Charlie

My past experience has been with British car SUs so that may be confusing me. I acquired my 1972 Z a few months ago and have been trying to fix several things the PO did not fix. One is the front carb is causing the first three plugs to become black and gummed up. When I clean the plugs they are black again after about 100 miles. The back plugs are a fine light grey color. In the past my British cars were leaned out by tightening the jet up to the needle. In all the three repair manuals I have for the Datsun, on carbs they focus on the air adjustments. With a Unisync I see both carbs are drawing the same amount of air so I think that adjustment is okay. When I reach under the front carb there is a wheel with indents that may be adjusted by rotating the wheel. I think that is the jet adjustment. If I rotate that wheel clockwise will that lean out the jet and fix my problem? Do I need to go back and start the air adjustment from scratch again? Is the air control more important than the jet on my car? Thanks in advance, Charlie

Thanks Dan! That is exactly the info I was looking for.

I have finally fixed the old air conditioning with a new rotary compressor and am getting cold air. There doesn't seem to be any direction on how to set the environmental control levers in the dash for the best use of the ac. Would someone please let me know where the levers need to be set? Obviously the heat needs to be off, but where else are the levers set? Thanks, Charlie

Jerry I like your low vin number. Once, when I worked at the local Datsun dealer, we had HLS30 00013 come and I once bought some race tires from Jim Fitzgerald and got to look over his HLS30 00003. Charlie

Hi, my name is Charlie and I live in eastern NC right by the Intercoastal Waterway. I am buying a one owner 1972 Z next week. It is in very good condition and can be used as a daily driver. Back in the mid and late 70s I raced a '72 Z in Solo II category of the SCCA, NC Region. In '78 I was fortunate enough to win 1st place for that year in AP class. Other than driving several Nissans over the years I have not had a Z car since then. I also collect British sports cars and have two Austin Healeys. A '66 3000 and a '59 Sprite MKI. I look forward to enjoying this Z because it is much more "driver friendly" than the British cars. I will be checking in and asking questions as I fine tune this great car. Charlie
