Hi all!

Here I am again!

 

So I fitted my new cam (yey) 

How Do I set ignition timing now? The original position of the rotor is gone( messed around while fitting the cam + had the girlfriend that turned the cam a few times 'to see it work'

 

Any hints on this one?

 

grtz!

Did you dial the cam in first?

It must be done prior to fitting the dizzy drive.

Dialing the cam, is that just like fitting and timing the cam? 

I fitted it with the dizzy drive still in place... 

 

grtz!

[jaydee]

yes, setting to the proper timing specs

[jaydee]

You cant really fit a cam with the drive in place

Yeah, needed to keep turning the cam ;p should I pull everything out again? Or can I just take dizzy out now to set ignition right?

OMG why not doing the things properly.. Anyhow now you need to remove and replace the dizzy shaft because its way out.

 

Go to min 3'00''

Cam timing is set roughly using the "dot-to-dot" method described in your service manual (Haynes or other).  Read up on that procedure and make sure you followed it (at least) before worrying about the ignition timing.

 

Once you have the cam timing set and the engine re-assembled, you can set the static timing of the engine (if you have points or most aftermarket electronic ignitions).  If you are unfamiliar with setting static timing, visit the link I will post below.  Sometimes I cannot get direct links to the documents to work but you will be able to browse the directory and manually download the PDF file if necessary.

Thanks, so I actually have to pull the dizzy out again? ( That's what I understand from the  5-6 th page of the PDF.

Can this be done without removing camshaf?

 

grtz and thanks in advance for helping me out!

Just remove the dizzy, remove the shaft, make sure cylinder 1 is a firing TDC (timing mark to 0 degs),refit dizzy shaft to conventional position.

Now spin the engine until the timing mark is pointing at the 8 degs mark and fit the dizzy.

Connect the dizzy to the coil, and a 12v bulb to the coil, switch the key to on as if engine is running.

Rotate the dizzy until the bulb light goes on, when the light is on you have the dizzy static timed to roughly 8° before TDC.

Secure the dizzy clamp.

Thats the first step, an 'initial position', once done you can further tune timing to max advance.
