Fuel in air box?
07/23/13 at 13:37:41

I recently bought a 1996 suzuki savage as my first bike. I was told it was sitting for a year before they started riding it a month ago. I took it home and tried to start it but the battery seemed weak so I tried jump starting it. During certain times I would pull on the throttle to see if might help and it would fire but never start. After a few tries we noticed gas coming from the exhaust so we stopped and let it dry out while we checked other areas. The air box was filled with gas so we emptied out the air box and noticed it was still filling up two more times before I turned the fuel valve all the way to the left. I believe the issue may be that some old gas got the valve or float bowl stuck. How do I fix it? Is there a way to fix it without taking off the carb?

If I Ever dont want mine to start, all I have to do is twist the gas,, it wont,, First, make absolutely Certain the battery is Hot & healthy,

I got the bike started. I thought it was the carb at first but it was a much easier fix then that. It was the spark plug. Since it was cranked three days prior I didn't think it could have been that. I dried out the airbox and got a new battery. I put the battery on earlier today and tried to start it and after trying a few times I noticed that fuel was still spilling out of the exhaust again and filing up in the air box. So I took a look at the spark plug just to see and there was carbon residue build up on it. Replaced the spark plug and it works fine. I would like a few recommendations on fuel treatment and something I can put into the fuel that can help keep the engine smooth running and clean.

Ok so there was a fuel leak still but it was because the float bowl was stuck from excessive buildup. We cleaned that out and now the bike chooses when it wants to run. We primed it up then set it up to run the tank and it cranked great a few idling hick ups at first but when it idols now it's fine. The issue I'm running into is the initial start. I will start if the engine has been cool for a while then put in either half choke or full and you have to apply a little throttle but if the engine cuts off after it started you have to wait until it cranks up again. It will turn over but it just doesn't want to fire after it starts and then chokes out

Nobody here, will be sure of anything until you do this test...
It will take you less than 10 minutes...
Then, we all know...

Professional mechanics have spent many hours and $100's of dollars doing unnecessary repairs and carb work, before finding the bad petcock...
We don't do that here...
Fuel problem?... Check the pet...First thing...
You came for advice?... Take our advice...
If it ain't the pet, we can continue... but, we have to know...

Think flooding. If it's sucking fuel through the diaphram into the intake, after it sits, the fuel evaporates. When you restart, you have a nice rich mixture to start but it's too rich once you get vacuum up because of the leak. It floods the engine out. You wait a few and the fuel evaporates, bike starts...cycle repeats.

It only takes a couple minutes to check it and you'll have eliminated a BIG source of fuel related problems. Do the check...all of it.

Mine started occasionally getting slobbering rich when I stopped and flooded out one time when I stopped. I did the check first based on advice here. Found I had an intermittent leak in the diaphram. It was very small but it was enough to cause problems sometimes.

These guys know their stuff. They've seen it happen so many times. They know right where to go to find the problem.
