The loop will sort of work until fuel goes through... Once the line is full.. If it's
down hill, It's going to go IMO... If your tank is at the bottom of the fuse, not
much you can do about it, if not you can make some pretty easy mods to lower
the tank... On my first UCD I lowered the Tk. by 1/2 or so, by oblonging the
firewall and trimming the tank saddle. On UCD 46/S82 #2 I left the tk. as is,
but I installed the stock engine mount up right in the stock location and instead
of mounting the engine on the bottom of the mount I installed it on the top( had
to mod one of the mount arms a little to get the carb to fit, but it was very easy...
the cowl fit with no problems and it raised the carb. by about 1/2" And tho the carb.
is still a bit lower than the Tk... She works great... Good luck....
Saito's run inverted pretty good IMO with some adjustment.. On some of my models
I "lighty" close off the needle after fueling and left sitting then reopen when I'm
ready to go....
