my personal preference is to use modifiers like MMC or LMC. some people think that makes it more confusing.

GD&T has nothing to do with this, at least not with what I'm asking...

What I'm asking is more analagous to 2F vs. 3B vs. 2UZ-FE...

I think the smaller new-generation 4-strokes are RC4. My dad's 530 has an LC4. Both his and mine are 2008. And it sounds like Tim has the same RC4 as I do, which means that the RC4 started in 2007?

EDIT: Marco - me too, that's why I had to throw in the GD&T acronym as well...

that's a good read, but I'm telling you, all you will ever need is the jd spreadsheet once you baseline the carb.

Yes it does, ok RC4 for sure then.

I received my new parts from JD, the new washer, o-ring screw for the fuel screw, and the #42 pilot jet. Draining my tank tonight, will work on washing it out tomorrow night and saturday, then diving into the rest of the cleaning.

If anyone likes searching for fasteners, the washer for the fuel screw is .200" OD, .120" ID, and .020" thick.
