MG Midget and Sprite Technical - Distributor
|Adjusting my timing again this weekend (this time with the vacuum pipe disconnected), I noticed that when using the timing light to find the timing the timing mark on the pulley was steady for a while and then disappeared and then returned. Am I right in thinking that my distributer is likely to be worn causing erratic timing? Or do timing lights do that now and again? |
I am using a new gunson light, can remember the model but it has the function that delays the flash by between 0 and 90 degrees so that you can dial in the amount of advance you need and then just adjust the timing marks to 0 degrees.
The engine was running smoothly with little or no variation is speed.
Thanks for your help.
|I have just found out some prices for getting my dizzy rebuilt.|
£160 from Dizzy doctor - well recommended and sounds good but 10 week lead time.
£75 Aldon Automotive - also sounds good but no recommendations that I can find.
Does anyone know the difference between the two?
This e-bay item might interest you:
Or ask about the Megajolt system. I know nothing about them other than it sounds like a good idea. Others here will tell you about them, an d I might learn something!
|Aldon can rebuild and/or re-curve your dissy to match higher CR.|
I can't see how your dissy can work fine for a period and then go awol, i.e. you see a consistent mark that disappears and then returns. Normally a worn dissy would continually scatter the mark around a mean position.
Seems that your strobe might go awol now and again...
|Why have one rebuilt when you can buy a new one for less? I got one the other year (albeit for a 1500) and it was under £100 - and no, it wasn't a foreign part!|
It has worked solidly through random chaos caused by dodgy carbs, and various other thrashings I have done to my car!
|If you're going to replace the distributor, why not go with an aftermarket electronic unit or install an electronic conversion kit?|
I've been eliminating points for years & totally please with the accuracy, reliability & virtually NO maintenance of the new electronic units.
It seems you've done quite a bit of engine upgrades, upgrade the ignition as well!

|i bought a powermax dizzy from simon bbs off ebay for £65, it has electronic ignition fitted. fitted it last weekend and it made a massive difference, i would reccomend them.|
|Well, there you go...sounds like a good deal!|
I know the pertronix dizzy I installed made a huge difference over my worn out Lucas unit.
