Carb replaced... ran better, but still not running right. Turns out the MSD dizzy had corroded, and the advance had become sticky. Timing all over the place at times, fine at others. Dizzy pulled, overhauled and back in. New carb dynoed.
After a frustrating few months chasing it, nice to have it running right again. Off to Eastern Creek last week and leaned on it. Photo's from WSID's website.

Drove it home and stopped at some lights. The exhaust note changed, and all my bogan dreams appeared to have come true... sounded like the small block had found 100 cubes and became a big block.
Careful examination the next day found one exhaust pipe had disconnected at the muffler. Drove it so hard I blew the exhaust off it*

Never a dull moment with the wagon. More drama with the lightning whirler.
It tends to sit idle for weeks while I am at work, then does daily duty (and gets leaned on) when I am home for the week. A few weeks back it started misbehaving. Fires up OK, does a run to Woolies and back no problem. But get it warm (like doing Woolies, then Bunnings, then Dan Murphys), and the fun began. Back off the throttle sharply from load and the thing would stall... and then not want to start. Either let it cool down, or crank till the battery is near dead and get it to fire. Cruising along with the engine warm and it would start running poorly, then stall. I got damn good at stalling 500m from home, and rolling the thing into the driveway with no engine running. Repeatable behaviour in the driveway when warm - starts OK, revs OK, but snap the throttle shut and it dies. No misfiring or hesitation - it either stalls dead on closed throttle, or whilst cruising it runs with low power for 10 seconds then stalls dead. When it's dead, it has fuel, and has spark.
I've got my money on ignition, and specifically timing. That MSD dizzy had been stripped, cleaned of all the corrosion and put back together a few months back. It got a new pickup at the time. I reckon either the pickup is intermittently crook, or the corrosion is back again and sticking the advance at full throttle-values (around 32 degrees) when it really wants idle value (16 degrees) or vice-versa. Cap off, and lots of soot under the cap. Advance appears to spring back and forth OK. Cleaned the soot, no better. Ran it a few times, and the soot is coming back.
I'm done with that MSD dizzy.
Bought an aftermarket version, and had the ignition bloke gut out the vac advance and module, same as he had done with the MSD. They both now run the same - chopper wheel inside fires the pickup, pickup fires the CDS ignition box, ignition box sends power to the coil, and coil sends lightning to the lightning whirler. Dropped in OK, timed up and thankfully did not do the Scintilla Shuffle. Starts better, and the first test run with multiple hot starts/stops went OK. Fingers crossed it has fixed it.
