Hi,

Offhand, fuel overflow could be brought about by:

• misadjusted/punctured float; and/or
• dirt/sand lodged in the fuel inlet valve. Often this fuel inlet valve is a pin with one end pointed (sometimes rubber) and is controlled by the float.

• short/jumping contacts of the starter switch;
• sticking/corroded terminals/contactors of the starting relay.

If it is possible to start at all. Fresh fuel fresh engine oil good battery. You may have the following problems; Corroded and blocked carburetor fuel system, bad wire connections piston ring set up.... I hope it was kept indoors and the fuel was drained out before it was left sitting. Good luck, they are nice bikes.

Check to make sure your getting gas by pulling off the hose, if no gas comes out your petcock is clogged. If this is the case blow air up into the hose, and if gas comes out now your tank has to be cleaned out.

Did you try to increase the idling adjustment screw?
Check the spark plugs for its condition and thn reset the air-mixture screw.
Standard procedure for setting air-mixture screw...tight it all the way in, taking care to not over tighten or the tip of the screw may be damaged, thn turn outwards 2 & half to 3 turns, start your bike's engine ,run it to normal temp. and the reset the screw + - alittle either way and you should notice the difference in the idling and all.
Its better too, to also check the valve clearance !
Hope this helps!

SOURCE: remove the carbs from virago 535

If your just interested in seeing if the bleed tube is clogged. you can remove the float bowls from the left side of the bike without taking out the whole carb.
