I'll try and keep this short. So, because of the voltage drop caused by the starter motor I decided to upgrade from the boyer system. Once installed, there was the odd backfire but no chance of running. Checked all was fitted as per instructions. Still useless. Contacted pazon because after measuring the difference between the pick up pins and the rotor it was obvious that the pick up pins on the circuit board were not reaching the rotor. AHA, A new board was available with longer pins but not free ? This helped but only if the motor span quickly enough. No kick start then ! When contacted again I was told that my camshaft was probably aftermarket and cheerio ? The boyer worked ! I solved it by cutting up different thicknesses of an old set of feeler gages and fabricating inserts to shim out the rotor. It now works !! Pazon did not reply when I told them the fix. Don't give up. There is usually a way out. Anyone else had similar problems, Roy.

You can solve the voltage drop issue by fitting an 8-48 v in 12 v out Inverter
Is there any side to side play on your camshaft?
From memory I think my mates MK3 camshaft had the thrust washer fitted the wrong way or missing?
And the cam was sitting too far back to get a signal for the Boyer pickup to work
 
So you have a starter kit or Mk3 1975 Commando ? right???
Go back to your instructions and do it again with the Pazon.
It is straight forward.
What is your voltage?

He stated in the title it's a MK3
And the issue is the rotor is too far away from the pickup coils
 
I once tested the Surefire on a lathe, and found that the distance from rotor to pickup coils is not that critical.
Even with the magnets well clear of the pins, it kept happily sparking at 2000 rpm (=4000 engine rpm)

The MK3 I worked on was fitted with a brand new Boyer unit
It would spark if you passed a magnet over the coils but not from the magnets on the rotor
I had to shim the rotor to get a signal
 
Pazon didn't make the backplate with longer pins for fun I assume. I also got the tolerances of pin to rotor distance allowed and even then they weren't close enough. 3.6mm>4.6mm from the outside of the board to the front of the rotor. Mine was about5.5>6mm hence fabricate some shims ! Roy.
 
I now have a spark to rival Blackpool illuminations. Rubbish before home made shims ! Reply from pazon . Pazon ign , mk3 commando. I had problems !
 
I kinda just took it to mean that he has a nice, good spark now. Either way nice going yaki - necessity being the mother of invention and all that- not sure if I would have thought of using old feeler gages as shims- nice bit of ingenuity. Cj

Where did you get that timing cover in your picture? The logo reads horizontal while the motor is vertical.
 
For some reason , before the homemade shims inserted , no sparks at kicking speed , plugs in. Plugs out , occasional sparks. When it actually fired up ran reasonably above 2000rpm, misfiring and cutting out at tickover. With shims, as intended sparks ! Boyer had none of this. Worked fine. It all started when Quest to make the electric start functional ! I had the pazon sitting on the shelf for a good few years waiting ! I attach photos of backplates and homemade shims. Thanks to all as usual, Roy.

Did you measure the length of the pickup poles?
I was wondering what the difference is?

This sounds intriguing, my Mk111 with boyer starts fine on the button, but not my A75 (electric start) and I am suspicious of voltage drop, and was considering a direct feed via a switch.
Do you have more info about the inverter or a link, as I googled and only got confused?
thanks

It's a Commando cover, the original logo welded in, and then grafted horizontal:

Pazon ign , mk3 commando. I had problems !

( I got fed up with remarks about the slanted logo..)

It's komando who should be thanked for this
He got me onto it
I got mine from eBay,I'm not sure if it's exactly the same make but it's this type
As long as you have 8v or more going in
You have a stable 12v supply coming out
Cheers
