If I read your post correctly you didn't say carbs you said carb. I would sudjest
against a single carb. If your intention was to say carbs you also need to add cam
to that list and possably dizzy also. Don't get me wrong I Love
my Webers
but there are somethings to think about. I did get better MPG with FI then carbs
a second consideration is re-sale. Now it has been argued that FI (set up correctly)
will give more HP in the right RPM range for a 914. I would never admit to that
(in a crowd) but some reliable sorces do use FI (not stock) and get some
respectable numbers out of their engines. So it all boiles down to your personal
preferances and pocket book. Welcome
