[Farmall] W 9 mag

[Ivan Cousins]

Well , he called tonight . Didnt hook anything up to the kill switch , so
looks like I'm back to looking for another mag . All the H 4 that I have in
the garage are plain , Rh drive , excepting for the one for the diesel and
the lag angle and such is different .   I thought for sure I had given him
the only other lh one that I had .
 Is it possible to just change the impulse coupling to make it work ?  How
is the  lag angle established ?   Thanks , Ivan
