What To Do With My Dodgy Dizzy
Posted: Mon Sep 13, 2004 7:16 pm
Hi all,
Just got back from a great trip round the Scottish Highlands. The only bummer was my Lumentition control unit failed. The local garage, at Loch Carron, luckily found correct points and condensor and we were on road again.
Whilst doing this it was found that the advance weights had seized (oops I admit it, I forgot the oil) and one of the springs wasn't even attached.
I have been in and out of the unit a few times now, with knowledge gleaned from Marcel Chichak's document at: <a href='http://www.telusplanet.net/~chichm/tech/lucastuning.pdf' target='_blank'>http://www.telusplanet.net/~chichm/tech/lu...lucastuning.pdf</a>, Miles Wilkins book and threads on this site.
Other faults discovered are:
Excessive vertical movement due to no nylon thrust washer.
A primary spring as loose as the secondary.
Next I need a strobe to check what the advance is actually doing.
However the 23D4 unit is inscribed as 41489 which doesn't feature in Miles book at all.
With the correct advance springs it should be fine, yes? However which curve should I have? The engine, according to my DPO, is a standard 105bhp Weber unit. So should I get the dizzy to match the 41189 curve? Our should I just abandon it and if so what should I go for?
A company called Holden will recondition but it takes three weeks and I need the car most days. Any body got a spare I can borrow? Plus what spec should I get them to recondition to?
