Hello guys,

I could use some advice on helping me understand just what I have here. Specifically, I have two identical Webra SPARK Thyristor-Zundung fur Modellmotoren. It also says on the module "Betriebsspannung: 4-6V.

This unit appears to be a spark ignition system with a spark high voltage cable and hooded Bosch plug cap. It has a 2x4x2 inch box with two additional sets of wires coming out--one with a black cable with 4 wires and one three wire with a RC radio type plug on the end. Unfortunately, there is no sensor set.

I am curious to know if these could be hooked up to a gas engine and add one or two Hall sensors and move from capacitance to electronic ignition. I was thinking that these units might have been made for the big Webra BX? engines.

Any thoughts on how to use these, how to hook them up, or where they came from would sure be appreciated.

Thanks for any help,

Tim

Made for the old Webra bully, best small gasser ever..
The sensor (4 wires) screwed into the back of the crankcase.The magnet is in the crank web, exactly opposite from top dead center. The ignition might be electronic advance..I have never tried to use the one I have, so am not sure,,A small engine like that doesn't need electronic advance anyway..

If you deside not to use the ignition I would like to buy it from you. I have an old Webra Bully that needs an ignition. I have been looking for one.

I also would be thrilled to have one, or both of those ignitions. Please let me know asap. Thanks

would you sell one of these buy chance? I need one for a bully.

Tim,

Thanks for the information offer. I traded the units for some servos and gyros to a guy in the South. Things worked out fine.
