Hello, i have a snapper frp216016 with starting issues. I cleaned the carburetor and it will start right up with starter fluid and will go all day but if i try to prime it then pull start it it won't start. took the primer all apart and put two gaskets behind the air cleaner, seems to prime nicely now but still won't start with the pull start. Any ideas where i should look next? Would it still be a carb problem? thanks for any advice.....
