Cool! Smiley glad you found the problem,was that a bad earth on the base plate inside the body?Hmmmm...so thats the rear clip hitting no2 plug? I had a look through my plug top covers in my bits boxes today. Some do seem to protrude more than others. I got mine from VWP ,they are rubber and form a good seal round the top of the plug to stop water getting in.I made the leads up and crimped and fitted the brass connector inside each one. I mustve been lucky choosing those caps then!I think I even had to carve a bit off one of mine to clear. so...could you re time it and move the body round one place on the cap,then move all the leads round to suit?

i could if i knew how the hell to do that. iv always had bikes and cars with electronic ignition. this is the 1st time iv ever had to play about with pionts, dissies, roter bodies. i know its a great learning curve but im bloody lost here or i could just take the body in2 work and skim the corner off the clip holder thats hitting the plug. i had no idea that i would have to move the body so far around. plug and play my arse

I have been pondering as to why some folk have difficulty with the distributor cap boss touching the number 2 cylinder HT lead due to having to turn the distributor too far round .
I think I have found a possible cause and a possible couple of solutions which I hope to post tomorrow .

I have found part of the problem as to why the distributor has to be turned round too far and it is caused by the vacuum arm . I will post a pictorial later on today  Smiley

Going to attempt to get article up as a 3 part post .

PART 1 of 3

POTENTIAL PROBLEM WITH THE DISTRIBUTOR HAVING TO BE ROTATED TOO FAR CLOCKWISE AND THE DISTRIBUTOR CAP CLIP BOSS BUTTING AGAINST THE NUMBER 2 PLUG LEAD

I have been pondering as to why some folk have difficulty with the distributor cap boss touching the number 2 cylinder HT lead due to having to turn the distributor too far round .

I took a few photos of the distributor , set up correctly in position , and noted the position of the peg which locates in the vacuum capsule rod hole  .

It is approx half way on the distributor cap clip boss when the vacuum capsule is correctly located in the peg .

PART 3 of 3

I then removed the vacuum capsule and disengaged the rod from the peg .

I re-fitted the vacuum capsule just by pushing in and tightened the two retaining screws .

I took more photos and the change in the position of the peg which locates in the vacuum capsule rod hole was obvious .

.
It had moved further round in an anti- clockwise direction away from the high point of the cam .

The points heel was well away from the highest point on the cam

Since the cam is stationary when you are doing a static time of the engine you have to turn the distributor body by hand in a clockwise direction to get the points nearer to the high point on the cam where the points will open .

This is why the distributor cap spring clip boss hits the number 2 cylinder .

SOLUTION ;
Engage the vacuum capsule rod in the points peg attached to the top plate.

If the rod is engaged correctly in the peg then might it be possible to slot the 2 holes in the electronic pick up thereby allowing you to move them nearer to the firing point ? .

I added the following info today 25 January 2012
https://sites.google.com/site/fifersrelianthintsandtips/electronic-conversions/how-to-fit-a-simonbbc-electronic-kit

ADDITIONAL NOTE 1 ;
I think the following modification suggested by R3W forum member " norfolkandchance "  is a worthwhile addition .

Fifer - you might like to add that its worth gluing the thin wires of Simonbbc proximity switch to the inside of the distributor away from the rotor with silicone.
The wires have a tendency to work their way through the rubber gromitt over time, tightening the wires across the rotor and eventually will rub through.

ADDITIONAL NOTE 2 ;
R3W forum member "Azzy" suggested doing the following
