Hello. I'm looking for information regarding the height of the standpipe from the float bowl sealing surface to the top. I've been having carb overflow issues into the engine. The fuel isn't coming out of the stand pipe( either one) as I believe it should giving proper float height adjustment. When I removed them today I measured the stand pipe height and found one at 5.59mm and the other at 7.83mm that seems like a big difference( 2.24mm) but I'm not sure which one is correct(strange that they are off by that much). I've cleaned the carbs in an ultrasonic tank several times gone through the passages relentlessly installed new carb kits from Scrambler cycle to include needle and seats new floats from CMSL adjusted to what I believe is correct at 20 mm. Yet they continue to dump into the engine. Thoughts? Maybe the new needle and seat are junk. I do try close the shut off valve at the tank every time but these aftermarket shut off valves are just not dependable. If any one has a set they could measure it would be appreciated. Thanks.
