Hi
You have a dirty carburator. Remove strip and do a good clean the jets as well. Look at dirt in the feultank the reason for dirty carb is dirty
Good luck

tank wasn't dirty...that's what was surprising. also the fuel intake pipes and screens were clean. Where are the jets, do I have to remove the Welch Plug and is this plug reusable?
 
Would you check a couple of things for me. You have what is called a pulsating-jet side draft carb. You said that you installed a new diaphragm. Did you make sure that the spring and spring cap were install correctly. This order, spring, spring cap, diaphragm, cover. If done right this diaphragm draws fuel up the long pickup tube from the main tank into the small resiviour tank. Second, pull the tank and carb and see if there is fuel in the small tank. I know this is a pain to do. If there is no fuel, then the diaphragm pump is not working properly and then we look at why.

I will check when I get home. But, when I took apart the carburetor from the tank the first time, there was only a diaphragm between the carb and tank. no spring and spring cap, I don't even know where that would be. I have the illustrated parts list for my engine and can't see anything between carb and tank.

my mower looks exactly like this McLane Power Mower

So, the small tank is fuel used during the start? and the long fuel tube is for during the operation?
 
According to you post you have a 80202 Briggs engine. The carb for that engine has a gasket between the carb and the tank and a diaphragm pump on the side of the carb. Do you have a diaphragm or gasket between the tank and the carb?

Part #272409S, gasket. I must of been mistaken if I thought gasket and diaphragm were the same. Ima lamo.
How much of a difference does this make? Still check areas you pointed out in previous post?

1. taped choke throat, and did not start.
2. fuel present in small tank (so diaphragm working?)
3. took diaphragm cover off, diaphragm doesn't look so good (see photo) but must be working in order for there to be fuel in the small tank. spring, spring cap, diaphragm, and cover present in this order.
4. gasket present between gas tank and carb.

diaphragm in photo is off a pulsa-Jet carb, and looks poor to me...! I would replace it.
Part numbers that I have for that carb are....
Diaphragm (1) 270026
Gasket to engine 27355 (2) are used
