replacement Ignition for 3W140 ?

       Remove this ad - become a site supporter!
I'm looking for a Twin Ignition unit for a 3W 140 Old style (Single Magnet hub)
or a plug in replacement that is compatible without a lot of fiddleing with timing

I have heard that DA/DL units are also compatible ... anyone know for sure ?

I have also posted in " Wanted Engines"

I would appreciate any help to find a replacement that does'nt cost an arm & a leg

Re: replacement Ignition for 3W140 ?

The DA modules are not compatible with the DL modules. The timing is different as well as the polarity of the magnet.

For your engine, you should contact Ralph at

He can point you to the right direction about the module that you require and also he will guide you in the "how to set" the timing for a new module if a spare is required.

I hope it helps.
