New Electronic Distributor for Wisconsin VH4D and W4-1770 engines with top mount (governor drive) distributors.  The distributor will only fit top mount applications.  Replaces D41-10B, YF50AS1, and IAD-6004-2P.  This distributor has a 14 tooth gear, be sure to count the teeth on your existing distributor gear.  This is a stock photo, the actual unit shipped may vary in appearance but will be functionally equivalent.  If you need a side mount distributor please contact us by e-mail or phone. 

For 12V negative ground only, internal resistor coil recommended. 

We have replacement caps, rotors, and modules available for this and other Wisconsin distributors, check our other listings for details.

Questions welcome and encouraged, we want to make sure you get the right part.
