I am finishing to rebuild a Euro specs engine with 2 HIFs carbs and a Lucas 45D6 distributor (vacuum advance) that allegedly has had very little use.
Out of curiosity, I opened up the distributor, and found only one spring on the centrifugal advance weights. The one spring has about 4 mm of play before it engages.
Does this seems legit, if should I look for 1 or 2 new springs?
Found a great pdf on the web from the MGA tribe.
I am missing the "primary"spring that should always be under tension. The “secondary” spring should be loose to allow the primary one to do its job in peace.
This is all nudging me closer to dishing out a wad of cash for a 123 setup…
But I will continue trying to crack this one for now…
