Thanks for the pointers Jeff. Here is the update on the bike. For starters I put in a new sealed battery so I should be good there for awhile. I must say that the stock battery has served me well. It made it 4 years of street and off-road use in which time I've ran it half dry a couple years ago and totally dry this fall. What amazed me was after I filled it up with water and gave it a charged it would start the bike fine with only 11.8 volts. Not sure how it did that but it would. I figured since it would not take a full charge it was time for a new battery. I pulled the float bowl off the carb and clean things up a bit. There was a little corrosion looking fuzz here and there but no gunk. The gas tank looked spotless inside. Something must have gotten hung up to cause the float to stick open. The good news is it's running like a top now. There is another issue though. Once the gas got in the crankcase my clutch instantly picked up 3/8" of free play at the clutch lever. Almost seems like the gas ate away at the fiction plates??? I adjusted it and took the bike for a 25 mile ride and it functions fine. However the gas in the crankcase sure seems like it did something to the clutch. I suppose have to inspect that but I need to rebuild the rear shock next. Steve
