Hey to all you carb guys. My problem started the other day while on a ride,my 91 running great,then at a stop sign it died,wouldn't idle. Started it up and keeping the revs up I made it home. I tried turning the idle knob,no difference. When running,I pulled the back cylinders plug wires,no difference. I changed out the plugs and it's now running on both cylinders but I have a hesitation when I open the throttle. It will rev up but it's not close to how it was running. Always ran some Seafoam through it,and never had any problems before. Any help will be greatly appreciated.
