"engine used very little last

"engine used very little last year and was misfiring, cleaned plugs prior to storing and it ran fine, this summer when starting it misfires again - I have replaced plugs, put in new fuel and a carb cleaner but it still acts like it is not running on all cylinders. Any help will be appreciated"
 
"Carb cleaner only goes so far

"Carb cleaner only goes so far, you may need to consider cleaning the carbs out completely. You may want to do a compression test and also check your fuel lines for cracks or bad connections as well as your fuel tank for a clogged pickup line. Over the winter the fuel could have gone bad in the carb plugging up the jets."
