What's with all this A and B stuff??

[Landmark]

i am glad you posted up this Simon, using your image to discuss.

Compared to many others I dont have much experience, nor have I seen so many 262 jugs that it mather, maybe 15.
I've never seen a 262 C jug or D jug.
Husky never had the options of ordering A B C D piston to 262, they only had one type piston, thats it, AB piston.
So why do Meteor offer 4 different options?
A jug, after worn out the first piston or second piston that A jug doesnt have A tolerance anymore, thats where all those 4 letters comes into play. If we take B cylinder we go one step up.
Hone an A cylinder, anyone think A piston is best match?
Those who follow the letter no mather what can do it for me, when my A piston is worn out it get an B piston.

Just my 2 cent about Meteor A B C D pistons

I believe you are right. I had the discussion with the guy i bought my meteor from and he said on a used A cylinder a B piston will be fine but if the A cylinder is new then match it with a A piston.

I'm not the expert here, but I think I have seen some who are expert post that there is not much wear on a cylinder, the rings are what wear. That said, if you have to clean transfer out of a cylinder like I did with my MS440, I'm sure that may open it up a tad, but not much.

At least you can easily tell what the machine tolerance is with Meteor pistons looking on Ebay and seeing a box picture is helpful Iv found .

As I recall it, their website tells what is what as well - but it is a while since I looked.
