Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hello,
I have a lawnmover with a tecumseh TVS9043388F engine.(SN 8222A) I'm having a hard time starting it cold. I've repplaced the plug, cleaned air filter, remove carb and bowl, cleaned intake port on engine.(bigh deposit in the intake section on engine) I've also taken the bowl off the carb and cleaned the needle seat, and sprayed the inside of the carb with cleaner and replaced the fuel line. After doing this the mower does run better when warmed up. (now it will stay running on low idle speed and won't stall in the middle of mowing the lawn. I did the seafoam deep creep spray while running the engine and plan to use seafoam in the gas.
This mower is a Murry with a date code of 0729. Any suggestions?

I own a Sears Craftsman mower with a 4.5 tecumseh engine. I change the primer bulb after a couple of years, especially if the 3x pushing does not start it. The bulb might look fine but it seems to spring a leak at the molding seams especially under the bulb. I am looking at a new Sears mower that has a self primer.
