Need local TQ expert

I picked up the carb again. The guy said there was dirt in it. Showed me a couple picks, so I thought ok, maybe. I changed the small amount of rubber line, mostly steel, and put in a good filter, i forget the micron number. I put the carb on, it fired up. stalled- thats ok, choke was open, kind of cold out. Turn again, sounds weird again, trouble starting, then bam starts up, I keep it about 2k till it is warm. Dies. Check carb, sure enough its leaking at the top. Look down the primaries, see gas, open the secondary, filled w white smoke, pull plugs- some are wet. Not buying the dirt theory at all. No way enough microscopic particles got in to block it up within two minutes and not one speck of dirt in the filter. This guy is bunk. So I try again w this carb or i get a demon maybe.
