runs very rough at idle, dies if you try to speed it up....put in new plugs w/correct gap, verified spark on all cylinders, new gas, check output side of fuel pump (all appears good)....doesn't seem to respond to the choke on the ignition switch...I'm thinking dirty carbs...but I'm afraid to take them off. I'm going to take off the "air-box" to see if anything is plugged...
Any other suggestion?
