I was given a Simplicty 4210 Lawn Tractor with 10hp b+s model 255707 type 0110-01 code 88041831 engine. It ran a little bit ( poorly) and now won’t run at all. It is an electric start motor, and with the air cleaner off and while cranking the engine, I believe I am getting blow back pressure through the carburetor (spitting gas out the air intake). Any suggestions in troubleshooting this issue?
