Here is a assembly/parts diagram. Hope this helps. gsx600racer, that looks like an IPL for the older type carbs with an adjustable throttle. The newer ones don't have the plastic butterfly in the area of the throat where the filter screw goes, an also thy don't have h metal lever that would operate said valve. The plastic throttle free carbs go together with the spring under the diaphragm, the diaphragm on the carb, then the gasket on the tank. All ofghm that I have seen are like his anyway. The older plastic an aluminum type carbs with the throttle and plastic butterfly go together like he above IPL shows. Not trying to come off as a smart ass, or a know it all. Sorry if it seems like I am. |

I have come to always blame it on the diaphragm. Their rubber compounds don't seem to have caught up with alcohol blended fuels. I've found I can get about 6 months out of a basic Briggs engine before that sucker wants replacing.
Except my current mower. I don't know what's wrong with it. But I only have about 200 sq' of grass right now so I use an electric weed whacker.

I was brought a 2015 WeedEater brand mower with a B&S engine. At first glance, the primer build was simply stuck in the pushed in position. At a closer look, the damn primer build had melted. There was red rubberized gunk all through the carb. IDK what the buyout in the tank,but I have NEVER seen that before.
My current push mower is an 09 Craftsman. Still on the OEM carb kit, and runs great.

2stroked, No worries. The diagram was for reference to how it goes back together. Without out knowing the engines model & type #, one can only guess what the correct diagram was. I based my guess on this one, I recently had been given and got running.  |

YES!!!!A REAL MOWER ENGINE!!!!!! I am not a fan of the newer throttle free designs. Almost useless. I usually find a way o rig a able to the governed to use as an adjustable throttle. When the went to the plastic carbs, the lost the big butterfly in the top if the throat, and the thy deleted hat slanted rectangle piece that covers the butterfly linkage, then in the end the diaphragm was changed, the metal arm was deleted, and then things were all re designed. The spring now slides in to a nipple on the carb, then the diaphragm is put on, then the gasket between the diaphragm and the tank.
Probably cost the B&S company millions of dollars t redesign the carbs an to delete t adjustment screw. Now if he carb screws up, there is nothing more than cleaning that we as consumers can do. No adjust ments, no jets, nadda. Its bull spit if you ask me.

Yup.
Here's the order:
1: carb body
2: spring on nipple thing of plastic carb body
3: diaphragm
4: gasket
5: tank.
Hope you get it going man. These throttle red plastic carbs are deemed a replaceable not repairable part in a ton o small engine shops. Thy don't cost much so its worth just buying a new one most times, especially since a shop will normally charge an hour for a cleaning an an hour for reassembly, an an hour t swap and an hour for reassembly. By he time you pa fr so hours ofsop labor, you can almost buy a new mower.
