Back to engine work today. I tried to mount the #3 cylinder, and found interference between the engine stand yoke and a cooling fin.

More importantly, I realized that the yoke blocks access of the piston pin for #3.

How to get the engine off the stand so I can work on the yoke? Without getting out my hoist, I built up a support from miscellaneous stuff.

Engine off. BTW, I did screw together the various bits of lumber.

It works.

Yes, I do realize I could shift the yoke to the other half of the case and not have clearance problems, but that would be too easy.

That let me mount P&C #3 and #4. I did notice that the cylinder on #3 seemed to rock a bit against the case. And after I did a quick deck height measurement, #4 was about .02 inch more than all the others.

I pulled #3 and #4 off, and found small raised edges around the outside of the machined surfaces of the case cylinder holes. The new cylinders seem to be a bit wider and are sitting on the edges instead of square on the machined circles.

I did not want to do any grinding or sanding, and so got out a sharp utility blade and trimmed the raised edges where they might interfere. That made the #3 cylinder sit square without rocking. I still need to work on the #4 seat.

This arrived today, from Mario at the Dub Shop: complete EFI and ignition system.


A very interesting thread just got REALLY interesting. I'm pretty sure my car is destined for this treatment so will be watching with great interest! (IMG:style_emoticons/default/popcorn[1].gif)

Nice work as always! Very interested in the EFI set up. If I can’t figure out my electrical gremlins, I may be going that route.

I know that getting the Dub Shop kit installed and tuned will take some work, but I decided that would be more fun, and give me better results, that fighting with the D-jet system.

I took care of the raised edge on the #4 opening, so the cylinder sits flat. And then I did a quick measurement of deck height, using my caliper with a T-bar attachment. My initial measurements:

#1, .068"
#2, .067"
#3, .067"
#4, .072"

These are a bit bigger than I want, and #4 is still trying to cause trouble. I need to set up and measure more carefully, and then see.

I got my cowl braces back from the paint shop.

I pulled the gas tank out again, and installed the right side brace.

Then I got out the frunk hinges. One of these was also at the paint shop.

I installed those with new pivot bolts, and a bit of grease. This photo shows the repair above the hinge I had to make since the PO let the original hinges get bent and open up into the cowl.

Here's my version of using a pry bar against the strut top bushing to pull the spring into place. I put the spring into the second notch for now.

Both hinges ready for the frunk lid, once I get the gas tank installed for real.
