Fuel running from breather tube....
.... That ends near the battery box.
'98 vn800a..... Bike has just been brought out from the winter. When I cranked it... It started but wouldn't hold an idle, then gas was running from what I think is the carburetor breather tube, which ends down near the battery box, and from somewhere near the heads. I opened the air filter cover and found a mouse nest behind the filter, not in the carb but in the air intake before the filter. I cleaned out the nest and tried cranking again, air filter cover off, same results - gas dumping from tube in battery box and the lower part of heads Soaked in gas and a small gas trickle from a tube at the bottom of the air filter housing. It won't hold an idle. Exhaust pressure strong coming out of one pipe, weak out of the other.
Any suggestions as to next troubleshooting/repair step?
