By theory You are all right, but practicaly the WBO worked perfectly on the
car. It reacted at the slightest adjustment of the mixture or alteration of
the needle/spring/oil/fuel level. I think under normal operating
conditions, the front cylinders are fed at least 90% by the front carb and
the reasr by the rear carb. I my opinion, we dont need any more
"perfection" on our engines. Working out the tree carb would realy be
challenging, though I think with a good balace-tool, it would still be
possible to achieve a good result.
