I had motor started a couple of weeks ago. Had no issue with starting. My ignition switch went out. Replaced ignition and would not start. I have spark at all 6 spark plugs. Gave the motor a shot of starting fluid. Motor fired right off and died. Had fuel in the carb bowls. Pulled the cover off the front of carbs, cranked the motor and could not see any fuel coming in. Should I be looking towards a fuel pump or at a carb issue. Any help would be much appreciated. Thank you
