this wont solve your problem but i see this alot. whenever upgrading stuff you need a reference point. always make changes in steps, this is how we would tweak my race car when we made changes to see what helped and what didnt. for example after a rebuild run everything stock to see where you are at. then add one upgrade at a time and test it. does it help/hurt? if it helps then keep it and try it w/ another upgrade did that improve thing more?. if you pile on with upgrades if youdo hit a hiccup you'll never know quickly where you might have gone wrong or which part does not work or might be defective. right off the bat the 30mm was too rich. remember bigger carb, leaner jet. as far as the top speed, not sure.
