Yep, That most likely has a float in it. It's easy to tell if a carb has a float, if it isn't mounted to the gas tank directly, it has a float. Now someone that knows their small engines may write in that diaphragm carbs don't have a float and they'll be right. But you won't find them on 4 cycle engines.
So a general guide to cleaning the carburetor. In not necessarily the correct order, here's what you can do. Remove the throttle cable. Remove the air cleaner and while it's still on the engine, take out the flange screws that hold the plate to the carb. They will be near the throat opening. I say to do this now because the mounting bolts to the engine will give you all the support you need to break them loose. On the bench the effort level goes up a lot. Pay attention to the governor linkage and remove it from the throttle flange. Remove and plug the fuel line. Remove the bolts or screws holding the carb to the engine. On the bottom will be a bolt with about a half inch head coming out of the float bowl. Loosen it up over a can of some sort because the gas will run out. Don't worry, just let it drain. Make sure the can is clean and you can get an idea of the junk in the carburetor. Once the bolt comes out completely, you can tap the side of the float bowl with something like the side of a screw driver handle. A hammer can deform the metal and you have to get a new one then. When you are tapping on the bowl, have it upside down. That way when the bowl comes loose, the float won't drop to the bottom and let the needle fall out. The float has a pin about a sixteenth in diameter and an inch or so long. It runs between 2 posts with a hole in each. The float has an opening for the pin to go through as well. You can grip the pin with your finger tips and it should come right out. It won't take much to get it loose. If it has set up over time and has the lacquer or varnish on it, spray some carb cleaner in the area and work the float up and down until it comes loose. Since your model has a primer ball, I wouldn't go soaking it in cleaner. You won't have a primer when you're done. They can be a pain to remove and replace so see if you can work around it. Spray the area in the float chamber well with carb cleaner and if possible blow well with compressed air. That should get you ready to run. If it ran well before I wouldn't worry about setting the float, but I can tell you how if interested. You may want to check into getting a new needle and seat. Unless you have a bowl gasket that's probably about all you'll need. Of course any time you mess with a carburetor, make sure to replace any filters. That's kind of like washing your car and drying it with paper towels... You just wasted a lot of effort. Air and fuel filters should be changed at least once a year.

I don't need brands and horse power. Just a short on what it looks like and how it's mounted. ----- Original Message ----- From: David Engebretson Jr. To: [email protected] <mailto:blindhandyman%40yahoogroups.com> Sent: Monday, March 23, 2009 1:18 PM Subject: [BlindHandyMan] rebuilding a carbeurator I've got a lawn mower that has been sitting for some time and would like to rebuild the carb. at least clean all the old gas out and give it some love so it will run well again. Any tips for doing this as a blind handyman?
