Thanks for thinking of it, but no.. Due to the crap gas they sell
around here (notably ethanol in the winter), I've changed my fuel
filter 3 times this last winter, and cleaned/checked the screen
filters twice.
I swapped out a carb piston yesterday - I've been having problems
with the rear carb needle binding just a teensy bit at the bottom
(idle). The piston has this little screw/gizmo at the bottom; the
only thing I can figure is it's for keeping the piston raised a teensy
hair above the throttle body (ridge thingy) :) . The Ztherapy one's
screw was rusted and below flush. The swapped one rotated and was
sticking out a hair above. Seems like it's a wee bit smoother, but
need to take it into town to try the traffic/lights..
Other things: I don't think I have problems with fuel return flow;
if I pinch the return line between the valve and firewall, the car
starts to sputter.
Am pretty suspicious it's *something* in the carbs, altho I have no
idea WHAT, since the problem existing with the previous carbs
too. Thinking about trying some kind of electric fan pointed at the
carbs; that eliminated the vaporlock problem in another roadster in
this area.
