Denis;
Thanks.
Chuck's a great guy and a great customer as well.
I used to live test carbs before sending them out but I've always been bothered by the fact that sometimes these carbs would sit for weeks, months, or longer before going into service again. Problem is once they've had fuel ran through them it's impossible to get them 100% dry again so the fuel remnants don't turn into varnish and the pumps, power valves, etc. don't harden up. As such I stopped running them live. I do bench test everything now though.
As far as float pinholes, they likely wouldn't show up even if I still live-tested them since they only run for a few minutes. The carb would have to sit full of fuel for a while before the float would start to sink (unless it was a really bad hole which would likely be noticed during assembly anyways).
Obviously I stand behind my work, and if there's ever any problems I'll do whatever it takes to take care of it.
