Default Re: G16 requires choke to start/run. How fix?

Well it is leaking air from somewhere, without question. Simple yet classic places, check the air filter, I read you changed it, remove the lid and check that there is a ridge where the lid compressed into to rubber air filter seal. If you replaced it wit a BU K&n style throw it away and consider it a lesson learned, replace with a paper filter or better yet a Carts Parts Plus re-usable air filter or Plowmans. Next once you are 110% positive that the lid is sealed, checked the 3/8 vacuum line from the valve cover to the air filter, just buy a new hose and two clamps… it is prone to cracking and does way more than vent the crank case. Next you can spray carb cleaner around the plastic carb neck that attaches to the carb and air box, if it's not cracked (you will not know until you remove the air box) They can leak at the base of the air box were there is a small rubber o-ring (place a smear of grease on it before replacing the air box). The carb cleaner MAY allow you to discover a leak. If not jump in and remove the air box, two nut at the base of the air box and two at the rear of the box, slide the assembly off the two carb bolts (carefully) and see what you have, you can make two new carb gaskets out of the back of a tablet (the carb board cover) if yours tore. The leak is there you just have to find it. With the carb off look to see if the tamper cover is on the idle mixture screw. If you are positive no-one has messed with it leave it alone, if not screw it closed and back it out 1-1/2 turns. Rarely should you need to use the choke for more than a second or to, most of the time not at all.
Hope this helps.
