this is on your mower then? i thought you were just messin with the neighborhood kids, oh well. wait, did the manufacturer sell one with dual carbs? at the scrapyard, you may find a smaller one that has the same head size, but lower volume, like a 160 head for the 200.

you might want to run a 2into2 with an x. it acts like dual, but because of the x, it breathes even better

"higher gearing" is numerically lower. ie: 6:1 is a higher gear ratio than 7:1.
As far as the cam lift/duration thing goes, I was always under the impression that a high lift/short duration arrangement was desirable for higher RPM applications so that the valves snap open and shut very quickly with minimal losses, Whereas a longer duration was good for the lower RPM's. Feel free to straighten me out...
