problem update

while manually opening the throttle I noticed the rear carb piston not going
up....I have removed the top , piston, and cleaned them up..had some
crud..reassembled...the piston does not go all the way down...if it does it
jams...mmmmm maybe the jet is set differently...if I lift it an open throttle
it lifts but not as fast as front carb....OK forget that, I learned how to
center the jet...now I need to figure ourt how to adjust the carbs....I figure
this bugger out yet
