assuming no mechanical issues and good crank case vacum ….like any carb it must be 110% clean to pass fuel in it’s LS and HS circuits . the 9.5 even more… 🙂

see these 2 videos and let us know if you actually checked the idle passage way and cleaned under the 2 plugs on top. a good cleaning also needs a small plastic insert.

the HS jet behind the lower bolt should inspected .. it must be 100% clean and.. pass light

the side knob (LS limiter) can be rotated a bit to keep the throttle from going… to low

see adjustement picture

for the missing carb base gasket you can always cut one up yourself.. .a bit tricky but doable if you can’t wait for snail mail delays

let us know how things work out
