Re: Fw: [T3] engine(carb) problems

Herman,
    I've been getting the same 17-18 mpg too, that's why I'm rebuilding the
carbs.  I've done all the valve/timing/points too.  I've also noticed that the
right side is running richer (plugs a little fouled).  That is my main reason
for the carb related theory.
    On my stock dual Solex '66, the air intake for the carbs comes from several
places.  There is a manualy controled flap that allows a choice of air from the
fresh air-cooling planum or from the engine compartment (winter use).  Also
there is a weighted flap on the underside that controls the pre-heated air
coming from the right heat exchanger.  The weighted flap is pushed open when the
engine speed increases past a certain point.  The last place the carbs get air
is the crankcase breather, but maybe this is just "fumes".
