Installing points
18 posts
• Page 1 of 2 • 1, 2
Hello, (again), I installed a new set of points and condenser yesterday on my +2 factory fitted with Strombergs. This is the first time I have done this job on this particular car. Because of the limited access and wanting to get the points adjusted accurately. I elected to remove the distributor rather than attempting in situ.
All went well, but wondering if this is how others perform this job. Getting at the pinch bolt and pinch plate to block bolt is tight but doable. But I figured worth the effort to bench set the points and knowing the clearance is correct.
Think I maybe cutting down an old spanner and bending it to make life easier next time.
Welcome others tips or advice. Thank you.

Personally I don't ever remove the distributor just to fit points.
I fit points with the distributor in situ, do an approximate 15thou eyeball gap, and then adjust/measure gap by Dwell angle, 57-63 degrees, this is more accurate than trying to adjust the gap with feeler gauges and takes in to account wear in the distributor.
I check Dwell on tickover and again at 3000rpm adjusting gap as required.
Usually followed up with an ignition timing/advance check with a timing light.

Always removed Dissy to change Points and Condenser in the past.
But fitted Simonbloc Hall Effect about 8 Years ago cheap and 100%.
Set of Points and Condenser in the Boot but not needed so far

I see I participated in the linked thread. Here’s an update.
When converting to Webers, coincidentally my Pertronix failed. So out came the dizzy and back in went the points.
Amid lots of other issues, much timing adjustment followed. Eventually I got so frustrated with getting a wrench on the clamp bolt that I pulled the dizzy and reversed the bolt, welding the nut to the clamp. Now the bolt head is easily accessed with 7/16 socket on a 1/4” ratchet. Timing adjustment is now a pleasure.

I was delighted to find my car on purchase had this mod carried out by a previous owner. I have many memories of misery with my previous Elan and Lotus Cortina back in the 1980s

Would you have a picture of this mod please….. I was looking at this yesterday and thought how much easier it would be with the bolt head nearest the block.

I do the same and it’s easy. You can only accurately gap the points using a dwell meter and even more important than setting the dwell correctly is setting the timing correctly afterwards. Ignition timing changes with changes in the points gap. I don’t know why some of you guys find it necessary to remove the complete distributor or needlessly modify the clamp.

Imho it's a personal choice if you remove dissy or not.
For me at 75 it's easier to remove and fiddle with small screws and feelers on a bench. Easier for my eyes and back.
Never used a meter to measure dwell angle in my life, again personal choice.
It's not a F1 engine.

One tip for dealing with small screws as they are almost ready to come out is to fix a blob of Blue Tack to the end of the screwdriver to hold the screw in place. Blue Tack is wonderful stuff with a lot of uses. I know there is nothing worse than that screw falling out and dropping behind the baseplate!

“Necessary”? “Needlessly”?
Neither word is appropriate here. Sure, it can be done either way, so clearly not necessary. But more convenient? That’s a matter of opinion, apparently. If our opinions differ, so what?
As for needlessly - it’s obviously not a matter of need, it’s a matter of convenience. You have to loosen and tighten the clamp whether you remove the dizzy or not, just to adjust timing. At least with my dizzy you do. And I think it’s inarguable that the bolt head is more easily accessed if the bolt is flipped. And if you have a MIG welder sitting in your shop, why not take few minutes and make the mod? But again, if you don’t think the benefit is worth the cost, good for you.

Very helpful discussion. I suspect I will do the mod too the pinch bolt next time I remove the dizzy.
Helpful to have a range of views and as also sharing knowledge helps us all.

But you have the Set Screw through the Slot for fine tuning.
If you choose to change the Points "without" removing the Dissy you only need to "fine tune" . So you don't touch the famous pinch bolt that if tightened too much breaks the Dissy omg.
