This kind of stuff is brilliant,
I have a plan for a big trip in mind for my M20 and part of the plan is to know my machine inside and out. I'm not a mechanic so I'm learning as I go.
Many thanks👍
Thanks John.
So of the 3 carb bodies I have all are stamped 30T on the bottom.
The top stampings are 39, 28, and one possibly 28.
Oh well .... I'll keep my eyes open around the jumbles for a 45 then.
The knowledge in this group is amazing thanks so much👌
