I don't have my motor right in front of me and need to make a tool for measuring deck height, anyone tell me what the head stud spacing is?
Thanks

I just measured a stock 1600 dual port and it is 3-5/8 inches outside edge to outside edge of the head studs.

 

Thanks! just checking but is that diagonal of side-side?

That is straight across from one stud to the other whether it be vertical or horizontal and that is outside edge to outside edge of the head stud.
