So when i bought this one the guy said he turned it off a block before stopping and allways used the center stand to park so that the left floats would not get stuck by the carbs being leaned to one side on the kickstand.
I put some 29 smoothbores on it and have now been still turning it off whenever i remember.
If i do not turn off the petcock then my garrage smells like a homemade bomb(probably as safe too),and there is some gas drips on the sprockett cover and floor.
When i get my new petcock will i still have to turn it off after riding even around the block and everywhere i ride????Explain to a dummy how my fuel system works to make this happen ..thanks folks ..it is a smelly drag for my friends..

They flood because you are not getting a tight seal between the needle valves and the brass seats.
you can fix that by turning the tips of the needles smooth and polishing the brass seats. If you get a good fit between them (and get the floats adjusted right), they won't flood.

Excess fuel being admitted into the floatbowl is often due to a "leaking float needle" which usually means an imperfect seal at the needle/seat interface. It's a good practice to keep the petcock turned off while the engine isn't running. Especially important with 29's which don't have an overflow circuit thereby allowing excess fuel to rise up into carb and flow toward air filter and toward engine.
Where crankcase vent hose is connected to a stock airbox, excess fuel getting inside air box from carb may drain through crank case vent hose directly into crankcase (this is bad). With pods, the excess fuel just pours out the pod filter.
Fuel from carb throat may also get into combustion chamber and flush past pistons into crankcase (just as bad).
Would sniff-test crankcase oil. Then change oil and filter. And not run the engine again until the problem is corrected.
Good Luck!

It's often grit and crud suspended in the incoming fuel that lodges in the float needle/seat interface and prevents complete closure.
Good Luck!

Fuel tank;
Petcock;
Any of several fuel line connections;
Connector at carbs;
Connector between carbs;
Cracked fuel line;
Loose or damaged float bowl;
Float bowl gasket.
While checking integrity of fuel supply, would also assure carb floats are not leaking or sticking, and check for correct fuel level using the clear plastic tube test (adapted to 29's large bottom float bowl mainjet access hole).
Good Luck!

I have had several bike and never had a leak, but my recent carb addition has been leaking . I replaced the float seats(tried 2 dif new ones) and they still leak so i have to remember to shut them off(remembering anything seems to get harder all the time.)
All u can do is try to clean or replace the seats and pray.Adding a good fuel filter will work in your favour.
