I took the bike apart to fix the starter clutch and now I can´t get it to run. It starts off of starting fluid. The bowls on the carbs are filling up with gas. For some reason it isn´t being sucked into the engine. I´ve tried everything and I´m at a loss. Could it be a vacuum problem? I´m not sure how these carbs works with the diaphragms. I´m used to the carbs on dirt bikes, if they aren´t sucking the gas from the bowl it´s because the pilot jet is clogged. Help!
