TC2 Restauration Project - A complete beginner's experience

Ok, there we go ...

For a correct ignition timing certain details have to be fulfilled ... I am sorry I have not found better photos yet, but I try to describe it a little better.

The piston has to be in top dead centre (TDC) position AND

Both valves have to be closed AND

the distributor rotor has to point in the direction of the cable to the right spark plug

AT THE SAME TIME !!

In your photos showing the camshaft pulley the little arrow is (as you have written) not in the correct position. This could only have the following reasons:

1. The crankshaft is not in the right position OR
2. The timing belt is not installed correctly, damaged or the wrong type.

First step: Turn the engine with a ring spanner or ratched clockwise on the crankshaft pulley until this pulley is in the TDC position. If you look at the front of your engine the tdc mark on the crankshaft pulley is the leftmost mark on the rim of the inner pulley.

Here is the index on the engine block for the correct TDC position of your crankshaft.

Would maybe a workshop manual in English help?

Then, if the crankshaft sits correctly, check the camshaft pulley again. Where is the little arrow now?

I think you have the correct type of timing belt because the engine once used to work correctly until it suddenly failed.

So please check first if it is possible to turn the engine until the crankshaft pulley is on its TDC mark and at the same time the camshaft pulley arrow is exactly on its mark on the front of the cylinder head then.

Afterwards we will take care of your dizzy ...

Please look at post #31 and then look at your engine to match picture, marks and pulleys.

Jörg is right (Thank you, Jörg!)

Here is another "picture I painted" (Suicide Picasso) for cylinder 1 ...

Yes, glad my picture was clear enough ... For the beginning it is sufficient to check / adjust Step 1 and Step 2 to find out whether the timing belt sits correctly on your engine. For the rest I will give you a few more hints then ...

Step by step, I think you will learn a lot in the next time ...

So everything has to be exact as on the drawing. Okay I understand, thank you

Cool! And now: set cable from Zylinder 1 on the position on your cap hows next to the distributor finger. 1 3 4 2 clockwise

Technische Fragen! Ist er und war er.

Zanzibar : This was just about the bookmark of this query.

Dann hab ich ein Bier zuviel gehabt

So you have found that your Timing Belt is ok, crankshaft and camshaft are in the right position / relation to each other, very good!

Next step.

Do NOT take out the dizzy yet. If you put a cap onto the dizzy is there a terminal vor a spark plug cable near the tip of its rotor?

Then you can put the cable for cylinder #1 on this terminal and clockwise the cable for cylinder #3 on the next terminal, then (next terminal) the cable for cylinder #4 and then finally the cable for cylinder #2.

Next step will be to loosen the clamp screw of your dizzy a bit and turn the dizzy a little until the terminal for cylinder #1 sits in the arrowed position in my picture below. Tighten the clamp screw again in a way that the dizzy can still be turned with a little "hand force" for fine adjustment.

The engine should start now and you can fine tune your adjustment while it is warming up. Only turn the dizzy slowly and just in small angles.

A picture comes in a minute or two ...

Zitat von Zanzibar

There isn’t a plug or terminal near the tip. It is between terminals 2 and 1.

Edit: I’m Getting good spark on all 4 spark plugs.

Edit 2: i did Jorgs test and checked the ignition coil positive with - on battery negative. Im Getting a 13.5 (Set on 200 ohms) with ignition off. If the ignition is on, there is no reading.

Good job! When the spark is there, fine. @ edit 2 it was a test with the blue tester in your picture or Voltage check with multimeter on DC not ohm

Yes ... the distributor position needs a little fine tuning. When I look at your picture you have to loosen the clamp screw at the bottom of the dizzy and then turn the dizzy a tad counterclockwise and it should start.

Exactly, thats it!

Keep it as arrowed, a little bit off the middle of the rotor contact tip. Watch out for the correct firing order. The dizzy rotates clockwise and starting with cyl.1 in clockwise direction the next terminal on the cap is cylinder3, then cylinder 4 and finally cylinder 2.

Have you got your timing light yet? (If not I would not drive the car yet.)

Another hint: The engine will probably run lumpy until you connect the rubber hose from the vacuum canister on the dizzy leading to the carburettor.

See yellow line in picture below:

There has been a thread about timing lights shortly on this forum and the recommendation was posted for a certain Equus model that I use myself. As this model has an additional ignition advance setting it is a very usable device for every work around ignition timing (measuring timing, including additional advance function, dwell, tachometer, voltage) !! The Equus is more expensive than other, more basic devices but very robust and, due to the versatile features it is highly recommendable and well worth the price, because you get in fact 3 devices in one. With your electronic ignition module you will not really need the dwell feature but if you use points it is mandatoy.

Maybe someone who recently bought it could let us know about the current price ... if you order via Voelkner it is around 110€ ... (see link above).
