Im pretty sure this is pretty standard 4an.
and this is what was underneath it, the restrictor is INTACT its hard to see because of the picture but theres a wee little pinhole in there.
I'm going to put it alll back together tonight. If it runs right good

if it fails im going to take it off and send it to FP.
Julien said he would pay for Half of it. Hopefully it works fine, if it doesnt hopefully he comes through ( I did give him $550, a 24pk of Corona, and a 60Trim for this 20g and $50 this week for driving.)
