Wb3a carb mods

hi guys, I am building a kt 100 on gas and wanted to get some info on flowing more fuel with a wb3a. thanks, chuck

Hi Chuck,

I raced KT for a few years also on gas/oil mix. I never modified my carbs as typically the trick is to limit fuel supply in balance with temperatures. Too much gas (opening your needle settings) typically resulted in a poorer running (4cycling) motor. Can you explain why you want more gas? Now if you were running alcohol you may need to do this but I have no experience with that.

You can lower the pop off pressure to flow more fuel and move the fuel curve around if needed.
