[QUOTE="Jez Nemeth, post: 158817, member: 3871"] Just left them there for setting up testing -will remove for a season -have a habit of going walkabout those adjuster damper knobs! ;) Righty, Talking with my electro expert (Who is presently wiring the interior of ScoobyVW with all latest led's/solar/gen upgrades)...coil is not possibly the right one to do the job well...there are coils and then there are coils... For twin spark, any twin spark coil will do, second lead fires and it's a lost spark, sparking into a fuel-less barrel on a twin, both HT leads fire at same time -forgive me if this sounds super obvious, but it's news to me... Presently, the hit from the spark is spasmodic -a bit of a lucky dip every so many, or many many revolutions gets it to right place for spark/fuel to create desired effect -the go bang bit. This sounds really familiar to what I'm seeing and experiencing, kick start roulette, game for the whole family... The Coil that would suit is a 12V with [B]built in ballast[/B], running down to 6v -ideally not in an oil bath, but the new Gel types are great, and cheap. The best sparks for starting are at 6v (which the ballast does at initial charge up). Once running the system is now looking for a 12v feed (Sparkrite or Bosch are good ones been advised). Without a Ballast, like the one I have -it's likely hit or miss with the coil. [/QUOTE]
