I am so thankful for this thread!

I?ve had an overflow issue for the last few weeks, which has become worse and also made the bike difficult to start. I?ve had the carb off several times in the last few days with no success, until I read and understood the information here.

Not sure if this is any help, but Ive place a 6mm and an 8 mm block across the mating face and scribed two lines on the metering block, which I?ve used to set the float height.

Thanks again to everyone who has contributed, I am most grateful.
