Default Re: Install new high tech throttle, bike runs 1 day

I don't know of any carbs with pulleys in them.
Throttle cables pull the slide up, spring inside pushes the slide down when throttle is released.
The only force which acts on the float tabs is the float itself.
You should only bend the float tabs as a last resort.
Check the little needle that the float pushes up into the "seat". It shuts off the gas from entering the float bowl when it's full.
Clean that mechanism out with carb cleaner after disassembling it.
One tiny chunk will prohibit it from seating correctly.
The simple NT carb is the easiest one to adjust, the others will try your patience.
