There's never a dull moment with Geo on the case.
Mind you, the same goes for Jasu... :)

Post Re: 1-2-spark
Thank you Ken. So today I made two brackets and welded them to the inlet manifold. Then I did a quick testdrive an my surprise my butt says there is more power. Going up hill I think there are 2 or 3 more hp now. Hmmm I always thought a spark is a spark... NOT.
Here is a little video of the day..

The coils are for a Renault or Dacia, but in general they need to have 2 pins, so 12 volt.

And no I did nothing to the 1-2-spark unit other then spliting the wites to run both coils.. I put the dwell down a little..

What resistance are your coils?

Mine have 2 pins and are 0.5 ohm!

The Rimmer Bros have some "special price" for Rover coils..:

There is a normal price, £96 but they have now £60 (included UK VAT) for six pieces, on their brochure what arrived by mail yesterday. Some Mega Clearance on their stock I think...

Post Re: �1-2-spark
I now drive a Citroen Visa engine and mounted the 1-2-spark from LPGo.
The wiring is simple. The mounting of the sensor which detects a metal pin on the flywheel is a bit more difficult. On top of the gearbox there is a hole in which a M7 bolt can be turned.The distance between the sensor and the pin has to be as small as possible (0,5 mm). Due to all components around the opening in the top of the gearbox, its very difficult to see if the distance to the sensor is small enough. But in the end one will succeed ! The mounting of the sensor for an 2cv engine is similar but there is no M7 hole available for a bolt.
In case you encounter a lot of misfires, check if you have sparkplugs with an interference resistor inside. They are recognisable from an "R" in the type indication. The R stands for resistor. These sparkplug will be needed in case "coil on plug" 's are used. These COP's should be connected in series.
