My ignition is dying
Posted: Fri Apr 14, 2006 10:07 pm
Evening all,
I've been working or servicing carbs and have got the engine going again. It was a bug$$r to start but after changing the plugs everything was fine. It has been ok for a few days.
However tonight I started it again and it ran well for 10 mins then ran rough, firing on 2 or 3 intermittently and finally died.
I swapped the plugs but no joy.
Fuel flow is ok and there is fuel in the float chambers. I took new plugs out after trying to start the engine for a few minutes and they were soaking wet. I put a spare set of plugs in and tried again - no joy.
So, the fuel system seems ok. I haven't moved anything so the timing is OK.
That leaves the ignition.
The spark seems a bit puny but more than that, it seems a bit intermittent. The ignition is lumeniton (the old optical system which is 20+ years old) and the box mounted on the inner wing gets very hot. Not having much experience with this system is this normal? The distributor cap is new (plus there is not any tracking on it) and I fitted a set of magnecor (blue) leads late last year.
Methinks it's time to retire the Lumenition and fit a new ignition (e.g. an Aldon + a new coil) but before I do that, does anyone have any ideas or opinions?
If I need to replace the Lumenition, what's the best system to replace it with?
One of these days I'll cure these %$?!! niggling problems and get this damned car back on the road properly!! Sorry, but this is getting on my ti!s.
Thoughts are very much appreciated.
Regards,
Hamish.
