Have searched internet extensively. WMK37 1 seems impossible to find. What's up ? WMK38 appears similar, if not the same. Can this carb use all the same jets, etc ?
Does the un-used pulse input need to be plugged.It is a fuel line attached to cowling, with a nipple on the end. There is a hole in it. Should the hole be there ? The pump is mounted to crankcase. It gets pulse from port , not the line. Thanks.
