Check air, then spark, then fuel

Air, spark fuel - that's the sequence that I learned from my MG technical sessions I have attended.  So I started with air - checked all valve clearances (no major problems but had to adjust 6 of the 8 to get consistent 0.015" gap).  Then checked compression - 150, 160, 155, 150 from front to back.  This is excellent.

My dwell meter pooped out on me, so could not really confirm points gap.  And could not then confirm timing.  All indications are spark is OK though, so I violated the tech seminar and went on to fuel.  : )

Pistons move easily, but jet position was way too low on the back carb.  Corrected that, then confirmed the fuel level in the jets is about right for both carbs, ie float levels set right.  Front carb did seem kind of dry, but it's float was set for deeper fuel level than rear.  I ran car in garage, idles fine and revs up fine, saw good atomized fuel flow into throat of carb when revving engine.  But took it out and it still bogs down and hesitates under load.  Decided to take up my friend Clay's offer to bring car to him and connect it to his diagnostic equipment,made appointment for a week away unfortunately due to our schedules.

Had a little more time to I tackled the logo on the trunk lid.  There are 15 little holes that need to be in the trunk to install the four pieces of the logo.  These were all filled in with body filler, so they were completely invisible on the outside.   But you could see them from the back side.  So with some trepidation I drilled out all 15 holes very carefully.  I also bought some plastic screw anchors which do a decent job of retaining the pieces in place, should be using a speed clip.  Here's a sample of the plastic piece:


Here's the backside after installation:


Those little pieces worked pretty well.  Here's now the pretty side:


Those white stripes are the lights of my garage.  Turned out real well!
