Hey guys. New to this board. Starting off by saying Hi. My problem is, I have a 77 cb750 I've had sitting for 3 years. Yesterday I spent alot of time trying to get it started again, but it just would not fire up. I noticed gas would come out the bottom of one of the middle carbs every 20 seconds or so....not sure what that means, but it drained all my gas. Got it going for maybe 2-3 seconds with carb cleaner, but would not stay on. Played with the tuning most the time though. Just no luck. Not sure where to start is pretty much my question? No experience working on these Hondamatic bikes.
Note: Has open exhaust if that makes a difference.
