how easy is it to clean cause im sure mine needs a good clean, is it a simple as taking the filter off an blowing through the jets???

 

It's easy to do take the top of the lid off the carb there's 4 long bolts that you undo just becareful that you don't knock the rest of the carb cos these hold the whole thing together.
May as well get a rebuild carb kit and do it all.
