we have an 88 warrior iv been working on all summer,its hard to start at first then runs fine but if you shut it off it may start right up or it may not start at all.it seems to have a decent spark,and sometimes the plug is wet and sometimes its not,iv changed the the coil,had the carb off and cleaned it out,replaced the flywheel key and starter clutch.it gets plenty of fuelhave this much at the carb and so on.oddly enough i didnt have this much trouble untill i replaced the starter clutch.
