[Healeys] SU Fuel pump points

[simon.lachlan at alexarevel.plus.com]

Basic question is: "How long, approx., should they last? (Yes, there is a
diode thing across them.)

 

My car has been running OK. OKish...I'd swapped back from Webers to the
three HD6s and had the car set up at the rolling road place. They leaned the
mixture settings somewhat, saying it would run better and use less fuel. (A
relative term). I noticed that it took much longer to settle down after
starting. Quite a lot of rude noises and much play on the choke at
intersections. And, when it was up to temperature, I wondered whether it was
quite right.was it a bit sluggish or was I just used to the Webers?

The other day, it hesitated and would have cut out. But, with one bound I
switched over pumps, and I was free! However, the pump - double ended - had
to come off for inspection. Both sets of points were completely shot. I
replaced them. Nasty, fiddly business. Now the car starts much better and
performs better all round. Surprisingly so..

I installed that pump in 2012, +/-12,500 miles ago. So that's +/- 6,250
miles per set of points.

1.	Would failing points give those symptoms? (I was/am surprised..I
though points either delivered 100% or failed 100%. I know that a judicious
thump on the bulkhead can work in the short term.)
2.	How long would you expect SU points to last?

Thanks,

Simon

 

Glorious weather here and forecast all week. Perfect Healey weather. One is
allowed out, but not really encouraged to go anywhere! Maddening. Pubs are
certainly shut. Anyhow, keep well.
