dont do a carb clean unless you have the tools. at the end of a clean you will need vacumm gauge to balance the cylinders and adjust the idle mixture screw. you may strip and clean the carb. but after that take it to a garage to get the carbs balanced. cleaning and striping on your own is easy, take it apart slowly and remember where everything goes. use compress air and carb cleaner, remember to take off the diaphragm before you start to use the carb cleaner. spray every hole you can find and use compress air to clean and blow away any clog together with the carb cleaner. do not touch the air cunt off valve... no need to clean that part, and it is a little bit tricky to put that part together.
