How do you set ignition timing on a Datsun 1200 Club?

Dwell setting affects the timing. To set the timing follow these steps: turn engine off. Set parking brake. Put transmission in neutral so that the engine will turn by hand. turn engine by carefully turning fan clockwise, until the timing marks line up (5 or 7 degrees BDTC).

Where is the factory timing mark on a Nissan?

The little mark on the Timing cover (black arrow pointing at it) needs to be in the middle of the section of the cas with the red curves arrows. That is the factory timing. mydato wrote: Have always timed DET’s at 10 degrees.

How to adjust ignition timing on a Nissan?

Discuss topics related to the CA18DE and CA18DET series engines. ok, to check it, i use a spark plug wire inbetween the spark plug and coil, then put the timing light clamp on the wire and point the light at the crank pulley correct? to adjust i use the CAS? just need some clearing up as i’ve never done this before. Thanks

Where is the timing light on a Nissan CA18?

Very easy to get close to factory timing without a timing light on a CA18 anyway. Goto TDC slide CAS in, do bolts up lose. On the side of the front CAS cover where the CAS slides in (right side) you will see a little dash right next to the CAS.

How do you set ignition timing with no timing marks?

Rotate the engine very slowly back and forth until the screwdriver is at the maximum height. This indicates the number one cylinder is at Top Dead Center or “TDC” on the compression stroke. Locate the number one spark plug wire on distributor cap and make a tic-mark of this position with a marker pen on the distributor housing.

What happens if you take the timing belt off an engine?

Warning: If you know you’re working on an interference engine, do not rotate the camshaft or the crankshaft independently while the timing belt is off the engine. You could cause the pistons to hit the valves, or vice versa, and cause the same damage as if the timing belt had snapped with the engine running — bent valves!

Where are the timing marks on a spark plug?

This indicates the number one cylinder is at Top Dead Center or “TDC” on the compression stroke. Locate the number one spark plug wire on distributor cap and make a tic-mark of this position with a marker pen on the distributor housing. Remove the distributor cap and observe the position of the rotor.

Where are the timing marks on the crankshaft?

For the crankshaft below, there probably will be a timing mark on the damper pulley that lines up with another mark on the lower cover. Or, the service manual may direct you to the transmission end of the engine to look through a hole in the bellhousing for a timing mark on the flywheel.

Where are the timing marks on a timing belt?

(2a) Find the timing marks on the flywheel and cam, and set them both to TDC. (2b) The flywheel pulley TDC mark is accessible through a hole in the bellhousing. (2c) The camshaft TDC is easy to find — especially if you add white paint as we did.

How do you line up the timing marks on a car?

A hydraulic tensioner takes care of this for you. Once the tension’s set, place a socket on the big nut holding the front pulley on and use it to turn the engine over — two complete crankshaft revolutions in the direction of normal rotation. Line up all the timing marks again.

Do you need distributor timing for ignition timing?

Engine ignition timing ( distributor spark timing) is the foundation of any tune-up. It is generally the first step you need to perform as all other tune-up and carburetor adjustments depend on ignition timing being correct. If you have the distributor out of the engine, see Installing Distributor . The exact orientation is not important.

What’s the advance tolerance for a Datsun A12?

The stock distributors have a mechanical advance tolerance of +- 2 degrees at the crankshaft. That’s a huge difference — up to 4 degrees retarded is still within specs — and is why you should tune your A12 for power. Whether a stock engine, or a modified, check this out!

What’s the firing order of a Datsun inline 4?

Almost all inline 4s have a firing order of 1-3-4-2 — and certainly all Datsun fours. First locate #1. The direction of rotation (Yellow arrow) is always opposite the direction that vacuum advance points (green arrow) — for all engines, not just Datsuns. Next, following the direction of rotation (Yellow arrow), count off 1-3-4-2.

What should the ignition timing be on a Nissan?

Adjust to 10 degrees, nip the bolts up and check timing again to be sure. I also always use a lead between coil pack 1 and the plug on all nissan engines with a coil pack setup.

What should the ignition timing be at idle?

When I’m tuning with Nistune or Live tune the timing at idle shows 10 degrees (even on a stock tune 8 port Jap head and ECU). If set at 15 then you will be 5 degrees advanced through out the whole timming map. Not really ideal when you are on the edge of the engines limits.

What’s the ignition timing on a 74 L18?

Then go counterclockwise from there…1-3-4-2. ’74 L18 it’s more or less 10 o’clock as viewed from the driver’s fender. ’75-’80 L20B it’s 180 to the above, about 4 o’clock. Because distributors are swapped so much see Pac above. ok I have 2 adjustment points on the distributor. one is for the retard/advance and the other is?

When was the last year Datsun made the 260Z?

The 260Z was produced for less than 18 months, from the fall of 1973 to the very end of 1974, and there were two distinct styles therein: the 1974 cars, and a three-month run of what are alternately known as either 1974½ or 1975 cars.

Is there a ground cable on a Datsun 260Z?

Only a very few 260Z-specific pieces, like the air cleaner (painted light blue on the 260Zs to symbolize the clean air of the emissions-controlled engine–no, really), will be tough. The factory battery ground cable is a difficult find, particularly with the second chassis ground strap for the firewall and the special battery connector.

What’s the correct setting for the crank timing marks?

The one with the marks is the main setting- when it is set at the center, that’s supposed to correspond to the proper setting (based on the static advance) on the crank timing marks. Since it might be a bit off due to gear backlash, wear, manufactiring differences, etc, the small adjustment is there to set “zero”.

What’s the best way to adjust the timing on a vacuum?

Continue rotating until the timing mark is in the correct position. Align the timing marks by continuing to move the distributor and checking with your timing light. When you’ve got it set where you want it, lock it back down by tightening the distributor bolts. Reconnect vacuum hoses.

Which is the direction of rotation on a Datsun?

The direction of rotation (Yellow arrow) is always opposite the direction that vacuum advance points (green arrow) — for all engines, not just Datsuns. Next, following the direction of rotation (Yellow arrow), count off 1-3-4-2. Here is the 1974-up distributor:
