SPARKBOX The EK Alternative™ is ALL-NEW and designed to be a reliable and “EK
onomical” substitute for the popular Wico EK magneto used on antique hit ‘n’ miss and throttle-governed farm engines. Use it as the primary ignition source, a backup in case a magneto fails or as a diagnostic tool to help rule out magneto problems when diagnosing engine performance!

                                      FEATURES
  • Mounts just like the Wico EK and fits within the original EK profile.  

  • Reproduction cloth-covered spark plug wire is routed through a custom lead-out tower, lending a vintage appearance.
     
  • Reliable, consistent spark!  Powered by a small, external 6-volt battery (we use an inexpensive lantern battery).  If you have a good battery, you will have spark!                                                                                                       
  • Tolerates worn magneto drives and eliminates magneto wear-related issues.   Solves common EK complaints like:  "it makes spark on the bench test, but not on the engine” and "works on one engine, but not on the other."                                                 
  • All-new, off-the-shelf electrical components.  Simple coil and condenser type circuit.  A micro switch eliminates corroded breaker points.  Adjustments or  repairs are simple and inexpensive! 
     

  • Works with all magneto drive types:  Type 1, 2 and 3.  Ignition timing is performed according to the engine manufacturer’s instructions.                                                                 
  • Tough, oil-resistant power cord.                                                                                                                          
  • Safety shutoff switch.                                                                                                            
  • Detailed, illustrated 9-page owner's manual.                                                                       
  • Limited WARRANTY included- request details! 


                                    SPARKBOX is for hobby use only.

Designed to work with all antique farm engines that use the Wico EK magneto, both hit-n-miss or throttle governed. 

                                           YOU WILL NEED:
- 6 volt battery.  We use an inexpensive dry-type lantern battery.
 
-  Proper length plug wire.  When ordering, specify the total length spark plug wire you need. Though it can be replaced by the owner, we install the plug wire here during assembly as it is retained internally and more securely than the original EK.  
12" standard length included.  Longer wire at additional charge, see below.

- Battery clips to attach the power cord to a battery. 
  We can install optional clips for extra. See below.


- Hardware of appropriate length (5/16-18 thread) to attach the
   Sparkbox to your engine.  Details in owner's manual.
          

         
                                            IMPORTANT NOTES: 

Spark wire outlet:  Plug wire exits the cover on the left hand side as shown
                              and is not reversible by the user as with the original EK.  
                              A right hand side version is available at additional charge
                              and extra lead time.

Type 2 Magneto Drive:  Timing retard may not work unless a lighter drive spring
                                       is installed.  We offer a spring for the Type 2 at a small
                                       additional cost.

Type 3 Magneto Drive:  Timing retard may also require a lighter drive spring for
                                       the Type 3.  More details are in the owner's manual.  

McCormick model M engines: 
          As with the EK, the SPARKBOX is mounted using one bolt and a special stud.
          We offer a lower mounting stud to fit the M bracket at additional cost.


NOVO engines:
          We offer the actuator (armature) clevis turned at 90 degrees to fit the Novo
          drive like original.  Special order, details below.

Internal Battery:
          There's simply no room left inside to fit a battery.

Using original EK cover plates:
          Although the Sparkbox overall dimensions and fit are the same as the EK, the  
         design requires a unique frame and covers, so original EK covers will not fit.


                Base price $350 plus S/H
          International orders-   write for details.

                                            Iowans must add 7% sales tax. 
                                    Request total before sending payment! 

 Please email or call first to check availability.  Prices subject to change without notice.
