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.

You forgot something .........

13.6@103mph. A little off the pace (13.2), but it had nearly 100kg of extra fuel-and-passenger ballast.

Well done team Harv.

Sits nice on the strip Harv- low 13's I reckon is pretty impressive... I'd be stoked with that, good job!

Out at The Creek last Wednesday. First run was a bit ambitious (red lit ) but remaining runs went well.

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*

* Disclaimer: there is a high likelihood that my shoddy workmanship let the bolts go loose. Don't tell anyone though... I like the "blew the exhaust off it story"

Harv, you NEED to be at next years nats with this thing, its going to be in N.S.W. somewhere I assume so a local one for you ????

[Errol62]

No excuses. It's only going to be about 413km from Greystanes, with a $10.43 toll.

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.

Cheers,
Harv

It’s amazing what can go wrong with ignition, and the problems it causes, modified engines particularly it seems.

Wagon ran find tootling around with it's new dizzy. Quite a few runs around the suburbs, all good. Picked up the meth-monster block from out Windsor way a fortnight ago, and did some "spirited" overtaking on the M4.

Mr Scott, Warp Factor 9.
I dannae is she can take any more, Captain! She's gonna blow!

At warp-speed, it was pinging.

Dammit.

Thought back, and realised I had only just fueled up, used an unusual servo, and the fuel reeked. Mebbe a crook batch of fuel. Tootled around for a fortnight at cruise speed, playing fuel tank level gauge Russian-roulette. Got tired of waiting, so drive it round and round and round the block on Sunday until is stopped, somewhat gracefully, at the side of the road. 20L of the good stuff from the long range fuel tank (jerry can), a drive to the servo to clean the lines out, then another 40L of the good stuff.

Another load test, and apparently I cannae change the laws of physics. Still pinging.

Drove it like I was driving Miss Daisy back home again, and put a timing light on it (... hindsight is 20/20... should have started here).
16º at idle (so far so good... at least the dizzy hasn't slipped).
Advance climbs with engine speed (also good)... up to 32º (yay!) then keeps climbing up past 40º. Aye, the haggis is in the fire now for sure .

No adjustment in the advance maximum, so nothing loose there. Either the dizzy pickup has suffered infant mortality, or the StreetFire CDS ignition box has crapped out (my money is leaning towards the latter). Booked in for Saturday to bypass the pickup to see if that is the drama. Points and a coil would have made it a lot harder to stop up the drain.

Harv

I don't usually give advice on sensitive forum matters, but I dont think you can go past the ICE setup. Plenty of dial up settings and great engineering (or so it looks to me). And locally made and supported.
