How far the float hangs down is controlled by this tab.
Wow. Having had a second look, I see what you mean. I never noticed that tab. Thanks for enlightening me. The tank and rear fairing are being painted this week and I have the carbs off for a different reason. I will have a look at that tab. Not to be dramatic, but this is kinda obvious but INVALUABLE info. I thought its all about the TANG. Apparently not.
Thanks.
