All clear so I can see if they are getting full.  If one gets full I can replace it or bypass it with just screwdriver. I have pressure washed the talk out and replaced all the hoses (at  30 years old they rot inside). That carb takes so little dirt to raise hell. By pass the mechanical fuel pump. Even a high quality pump will fail don't know why but in 20 years I have put 3 in. I replaced it with a high quality electric pump. Mount it high and away from the engine for fire reasons. The carb is easy to clean on the engine (remove the float bowl) Multiple clear fuel filters in series is the answer I found. Good luck I hope this helps. I have 642, 643 and a 743b all rock rock 743b!</p></blockquote><p></p>
