New sensor (on the right) ready to install and test--but dinner time.

Well, dinner turned into an extended absence. But I am back!

Lots of stuff delivered while I was gone, including a 3 ft length of 5 mm hex. Why?

This is a tool to finally repair my hydraulic press. The hex has to reach inside a 12 inch long spring in order to screw down the end retaining Allen bolt. Even the extra-long Allen wrench I have will not reach.

With the spring bolted to the bottom of the piston, and the piston inside the cylinder, the next trick is to pull the spring far enough to screw in the upper anchor. Definitely a three-handed job.

Somehow I got the second Allen bolt in with only two hands.

Nice to have the press working again--especially the auto return.

Back to working on the 914. A warm-up with dual outlet for the heater blower.

Then I moved the wire leads from the Hall sensor back to where they were in December, to match the one-page diagram of the lead connections (and confirmed by Mario).

It works! A quick calibration, and now I have consistent 0 to 100% opening.

I then tested the ignition spark with a spare plug, and now have a healthy spark with the engine cranking.

While on a roll I hooked up my timing light and tried to check the static timing, again with the engine cranking, but could not get a consistent light flash.

Just a few minutes to play 914 today. I did stop by a tire shop to have one tire removed, from the wheel that will be my spare. This rim has the worst curb rash.

After a quick clean, first with detergent and then Simple Green. Still some work to do.

Then a length of high temp hose, cut down to fit.
