Hi all
Wonder if anyone can help please.
I picked up a Hyper 7 complete for my son (2nd hand)
I reset the needles to Factory settings because i don't know what the last owner used for fuel.
In the manual it states HSN 3 1/2 turns out and the LSN 2 turns out. But there is a 2nd screw thats on the end by the fuel inlet is, Now i have set this flush and turn the LSN all the way in, Now as i wind the LSN out the Screw that's below the fuel inlet winds its self in at the same time and if i wind that screw back out the LSN changes as well
So for the life of me i can`t get this beast to run right, it starts straight away but give it a quick burst of throttle she shoots off then stalls.
There is no reference in the manual for this other screw, but found a manual for a Hyper .21 and its the same carb and it has ref to this screw
