correct...

the cable in the top is for the slide ... throttle.
the other cable on the side is the choke...

a pumper carb dose not have a cable to oparate the pump
" there's prob some chinese bit of junk that dose "..

What dose a pumper carb do ?...
It gives a squirt of fuel into the motor when you twist the throttle
to richen the mixture for faster throttle responce....

Injected motors like the RX3 have a closed & open circut they run
on the closed circut but when the TPI sences a throttle movement
it jumps the the richer open circut...

so the pumper carb is a mechanical version of the closed/open circuts
in a injected motor...

For you RX3 owners heres a little trick so you can richen or lean the fuel mixture
at the turn of a nob....

Put a 1 ohm pentometer in one of the wires to the air temp sencer in the air box..
then by turning the nob you can tell lies to the ECU about the air temp...
tell it it's colder & the ECU will richen the mixture.. more power/use more fuel
warmer & it will lean the mixture.. less power / use less fuel..
the ECU still works as normal but at a higher or lower range than what it
normaly would with out the pentometer...
The ECU will have built in peramitors that it can not go out side of no matter
how big the lies are you tell it... no chance of doing the motor in...

i have one on my XT660R.....
