Re: Mks 2 and 3 ignitions voltage

And I should have added that you can’t test an iridium plug for continuity as you can a copper cored ab6 or d16, because the core from top to bottom, through the ceramic sheathing, is not continuous - apparently , so said the Ngk guy in technical advice, it has minute gaps in it, which are so tiny t...

Re: Mks 2 and 3 ignitions voltage’s

This thread was left unresolved, so here is what happened The problem was that I could not start the restored 1969Featherweight . I built a test bed from a base plate and coil and flywheel so that I could actually see the spark - driven by a battery drill on the top of the flywheel which meant I cou...

Spanner jaw sizes

Now here’s a bit of gold for newcomers to this web site! It’s a very well researched, comprehensive, well structured and well drafted compilation of the different jaw sizes appropriate to the different bolt sizes and systems . As far as I can make out, the author Paul Crawford was an engineering lec...

Re: Mks 2 and 3 ignitions voltage

Oh and I missed out that the Petrol tap comes from George at Villiersparts - sorry about it not being original, but I wanted something that would not leak, looked ok, and had that rather unusual thread on one side, for which I could not get a tap or die.... I also put a longer screw at the bottom of...

Re: Mks 2 and 3 ignitions voltage

HA that is a very kind and generous comment, if I may say so, which I value greatly, having seen your photos of what you do! The only thing that still doesn’t look right is I couldn’t get a proper gloss on the black tank - I tried a large number of sprays with clear from the local automotive supplie...

Re: Mks 2 and 3 ignitions voltage

Thank you both so very much for the missing logic and info that makes it all crystal clear Hopefully photos attached (having size problems) that show instructions (which don’t contain Charles’s essential logic at all) and the EF and the 1969 mk 2 featherweight I got completely the wrong end of the s...

Mks 2 and 3 ignitions voltage

Can anyone tell me the output voltages for the above?
I have just bought the bit in the photo and one alters the gap according to the voltage
Also the Button on the end unscrews so you can put a spade end onto an m4 screw
Yes I know I can do it the old fashioned way but this looked better

Re: Checking a mk II coil

Still nothing on A to B or A to C
Interestingly, on the 200 scale, the B to C measurement goes from 0.3 points closed to 1.3 points open, so something is working!

Checking a mk II coil

I attach photos of a mark 2 ignition and the supposed way of checking I think I must be missing something obvious but here goes I put a voltmeter on the 200 ohm scale (the minimum) on the bit jutting down (ht lead receptor, point A) and on fixing bolt to base plate point B Should be 4.78 and I get t...

Re: V ring seals on prop shaft

Thank you for that - all very good points, to which I definitely do not have the answers, and which I have to resist the temptation to chase them with speculation.....!!
