POS!
ok, yes, it does the job until i find a mikuni 18 2nd hand... (all the good old moto wreckers have vanished!) or see if a diaphgram carb can run with gravity feed and no pulse... or make a pulse feed. and when i make my mind up what to do
but, ive had a tinker and got out the old chisel
mods i did.
machined the throat! its now a nice taper from the inlet to the face of the slide. increased venturi effect rather than the standard parrallel throat.
made a new jet! lathes are handy and so are multiple parts
and 0.05mm increment drills....
so, for my application, zbox 48, ive found !!!!!!! 0.6 to 0.65 ideal !!!!!!, down from...0.78? iunno. bigger than 75 smaller than 80... big difference
especially on fuel consumption...
bashed the choke flap bolt/nut so it doesnt come loose... yes, could remove and plug the hole...im lazy when i gotta be elsewhere!
um....
had to do more than bend the tangs on the float needle. found they hit the brass inlet barb! the needles groove was too wide, so...trim the brass barb!
thats it.
