We've been housesitting so unable to check it out again, I have a feeling that part of my throttle spring got caught in the winding, and its stopping me from tightening the shaft down fully, making it leak, I can't find a gasket in kelowna and there's a 3 week wait for them and a $25 charge to order it. On top of $7 a piece.
I made my own and it helped quite a bit, 2000rmp idle to 1250, I'm tested everything else, no leaks, but I just think I can't see it under the spring. I was going to rebuild again, but then got to looking at these, they look fancy, I saw a number of 80mm but that's just stupid big, I figured the 70mm is close to my 2" intake piping and I could port my mani to at least 65mm. I think your completely right john, the major change in my custom gasket has to mean that that is the problem.
