It is marked;

N149
06173 GM2568

So it IS a GM part after all.

Shelved the sensor idea for a while in order to get the car finished and running the old fashioned way first.

I noticed that the connector I made at the bulkhead was getting very hot when cranking. I am not sure it it was this connection at fault because when replacing the cable I found it was a bit loose on the starter too.

So to be 100% sure I fitted a fatter and better quality cable at the weekend and passed it directly from the battery to the starter. Then used another cable from the starter to that bulkhead fitting I made.

That seems to work better.

I also finished breaking in the camshaft at the weekend. It seems to have gone OK.

After, while the engine was still hot, I checked and adjusted the valve lash. It only needed a very minor tightning from where I had guessed the lash should be when cold.

The last time I tried to break in the camshaft the engine had ran very lean and damaged the finish on the ceramic headers. Pity that.
It turned out I had "guessed" the correct float level on the center carb way too low. It was leaning the mixture out.

My back was aching after doing the lash settings so had to stop. The next job is to set the timing exactly and see if I can get the idle nice.
I think i will wire up the LM-1 meter so I can monitor the air/fuel mixture while I am doing this.
But to wire up the meter I first need to wire up the cigar lighter so I have something to plug into!
The wiring for this is not included in the Painless kit so I have some 8A wire to fit to it.

been having a look for a data sheet

??? can't find one.

anywhere


most annoying


anyway the freescale one is nice from an easy to implement point of view

Because I gave Diana the job of filming the engine while I started it up and I got a 2 min recording of the front fender....

I found that bit of footage quite delightful.

Well done Dave!

I can't wait to drive through the Tyne Tunnel on open headers.

you should bring your camcorder along for that one

Sounds Fantastic, Great Work Dave.

.....so how much more to do till she is finished Dave.

The most eagerly awaited car in the club mate.
