#1 any improvement in gas milage,how much?
Mine went from 16 to 22 mpg. (Dual setup wit Offenhauser)
#2 installation,how trouble free?
got everything from Tom Langdon. Offy, adapters, linkage. A bit of bending and fiddling with the linkage bu no big deal.
#3what kind of choke does the holly /weber have?
They have water chokes with electric assistance. I converted it to manual (15$) cause I´m a controll freak. But to my surprise I never had to chock it (well it is not winter yet)
#4do you feel doing the conversion is worth while? Oh yeah!
better milage, better response, many jets, good to tune. Runns great and I love the extra kick when the second stage opens. Like a afterburner :p
