The square tube will probably be directly over to uprights... you'll have the 'plate' that will come up the aft side of the uprights & halfway up the aft side of the square tube, if that makes sense... But back to your original question, with the fuse level, drop a plumb bob from the cluster and you'll want the 'centerline' of the axles to be 6 inches forward from there... Hope that helps...
That helps. Always wondered about the 6" reference. Read a few comments on it but never had it clearly spelled out as to where the 6" started.

Brock, I know I made a seat.  Somehow. I thought I'd documented it, but searching didn't find it. I did find this: Everyone's seat is different.   From reading of people feeling they were sliding forward using the stock dimensions, I added a couple of inches (or more)to each end. That is working well, with none of that feeling. That said, from the top of my longeron to the bottom of the seat unloaded is 3 7/8 to 4 inches. There is plenty of clearance if the stick assembly is made per drawing..

Nice. I'll no doubt go into the rabbit hole looking at your nav app.

OK, I admit the pictures below don't look very much like 'wheels or landing gear' but hold on a minute.
I got distracted from making the seat when I realized having a seat is not very practical without something to hold the plane onto the ground. A crash from two saw horses in an airframe with out wings would be embarassing to explain. So I decided I'd have to bite the bullet (sorry Bullet no pun intended) and get to work on the gear. But I soon came to an obsicle of where to put the gear. It's hard to reference the leading edge of the wing if there is no wing. Thus the mockup picture below, my Landing Gear Reference Tool. After all that really is the first use of a wing right?
So for those of you in the know. Does the positioning of the wing look about right? (except for being a bit high) I really want to get the airframe mostly done before starting the wing.

I did searches using idle, jets, vm28, mikuni and a couple more variations and didn't see that post. Thanks for the info.

I've verified the main (200) and the idle (60) jets in my new vm28 carbs from Summit.
Also, I had ordered a 42 piece set of aftermarket jets from Amazon thinking that they would work. Well, they aren't even close. Under magnification you could see the holes weren't even close to the mikuni jets. If they have a number system that corresponds to anything it isn't supplied.
Obviously I need to get oem jets to keep from getting completely out in the weeds.
Going to start with 150 and 160 main jets and 40 and 50 for the idle circuit. I don't have a egt or a cht gauge so I'm going to go mainly by plug color and rpm with a smooth transition. Still open to anyone sharing what combination of jets they're using also.
