914World.com _ 914World Garage _ 914 4 1.7 timing

Posted by: HeloMech Jul 28 2006, 10:30 PM

Ok,

I'm trying to decipher what my timing is at. this is a 73 1.7, stock with djet.

Take a look at this crude drawing. At idle, the timing light shows the thick fan 'blade' right about the red dot at the rear notch. As I increase throttle, that thick blade and red dot head towards the passenger side of the car. From what I was told earlier this evening, that's the wrong direction. Is my timing retarding, is my engine running backwards (aieeeee!!) or did I just misunderstand the previous information?

What is the actual advance wanted at 3500 rpm's and where on this fan would that be indicated at the notch?

thanks,
Robert

At idel thats to much advance. The red line should be in the notch @ more than 2500RPM. Clock wise rotation of the dizzy is advancing. You need to back it off(counter clock wise).

The Red mark is 27 degrees which should be in the "notch" at above 3000 rpms. At idle there is a little white mark if present for 5 ATDC showing or not, who cares. Set the timing at 3500rpms with the timing lite as the advance setting is all that matters.

Read the pelican article as DD suggested. After that here are a few words of advise.

This is what I did.

Go buy a timing light with an advance on it.

Rotate the engine until you find the TDC mark on the fan. Mine had what looked like a strange infinity symbol on it. If it is faint borrow some nail polish and mark it well.

Set your timing light to 27 degrees advance.

Loosen your throttle cable (so that you can easily hold the RPM's to 3000).

Adjust timing at 3000 - 3500 RPM using the TDC mark.

That's it your done.

Edit - I did not include the plugging the vacuum line in my directions I assume you know that after reading the pelican article
