Stromberg Carb tuning


What kind of fuel pump? Check all the all the throttle
and idle adjustments, there is a certain sequence to setting up the idle and
doing the initial setup of several intermingling parts. Did your guy set that
all up for the GT6? I don't have the factory manual in front of me but there
is all kinds of specific turns out to start at like three turns out for one
screw and theres all sorts of sequences for setting various stuff that have to
do with the throttle stop screw? Did you follow that when you put them back
on? Some stuff is done cold and some is while hot and then you twist it in to
a certain rpm. I'd try to do that whole set procedure by the book. But perhaps
you already did that? If not, let me know if you need the guide..

20 weight oil check, pistons fall evenly and click
check, All emissions controls holes blocked? Check, camshaft timing,

you hold the pistons up and let them fall? They shoul both
fall evenly and all
the way down and click when it falls to the bottom? This
simple check can
