Thank you Chris for the reply, I have used the work toilet cleaner on carbs and it works fast in just a few minutes on the aluminum venturery a freind let it set to long and it eat it up.  I get a sealer at the local honda shop I think it took 2 qts on the 1650 tank. Its been so hot down here that work out side stopped, temp and heatfactor was114F. Made it to the summer show sat. afternoon late got caught in St. Louis for an hour from tearing out 270 still really enjoyed the show, it was great I know the rain did dampen things a bit too. Better go hope to see you again at another show and say Hi to the family and be safe this fall.   Boco
