Hello again, Ok so I can almost guarantee the carb is your problem because even after putting fuel stable in system it does not always keep the carb from getting varnished up. Thats why draining the float bowl is good insurance from having this issue in the future. Now as far as cleaning the carb its pretty straight forward, basic hand tools, good quality carb cleaner, air compressor, possible carb jet probing tool.
Remove seat and the carb will be located toward the back of the machine, the airbox tube and clamps will need to be removed, then remove the throttle cable, unplug the choke, then unhook fuel line, leave breather tubes that are part of the carb on the carb when you remove it. Once carb is off, look at the float bowl there you will see a flathead screw loosen this so that the fuel drains out. This is the same screw you will want to use when you store the machine, there should be an access point from the outside of machine so you will not have to remove carb to store it. Next remove the float bowl, float and float needle and pin. Then remove all jets, use your carb cleaner and thoroughly clean the carb passages and jets, if its really bad you may have to soak it for awhile in a carb solution. Next use your air compressor and blow out the carb and the jets, look threw the jets and make sure you can see threw them and no holes are plugged, pay close attention to the small pilot jet. Install everything in reverse order and you should be running like new again. While you are in there check fuel flow just to be sure its getting sufficiant amount of fuel to carb. Replace spark plug. If you need any assistance during or after just let me know. Thanks and Good Luck, Mrmocycle
