You could be right there. I did have it running pretty reliably but also have a faint memory that it would do odd things like cut for no obvious reason sometimes. And the MDS carb makes the GMS one look high quality in comparison. There isn't even any O ring on the HSN, no seal at all.
And the connection spigot on the GMS is 13mm whereas the MDS is 12mm so not a straight swap but I think I'll shoehorn it in there all the same and see what happens.
