Well, here's the update for today. Everything is together and it started on the second kick. Engine sounds tight, the Toomey's sound great. Went through a couple of heat cycles and decided to go down the street and back. Engine pulls hard (only went to 2 nd gear and half throttle). When I got to the house I noticed the right carb is leaking fuel from the overflow. I'm thinking no big deal, just a simple float adjustment or some trash in the carb from sitting. Here it is 2 hours later and the leak from the bowl overflow is only worse. I used my Yamaha Service Manual for my specs on float height and checked it to or three times. I also used carb cleaner and flushed the entire carb three times. Still, when you turn the gas on, it flows from the bowl overflow, and now from the other two vent hoses. I'm about fed up for the night, will try again tomorrow......Any help or advice is more than welcome.
