16.5 hp Briggs and Stratton I turn the ignition switch and flywheel only turns 1/4 of the way around and stops. If I keep turning the key eventually it will start and run strong . 2022 a new battery, solenoid ,ignition switch its started normally from Oct 2022 until May 15 2023 now its acting up again . I ordered a new coil .

the forum never poster my whole post new Die Hard battery 2022 I tested the battery its good . I put in a new solenoid 2022 , new starter a Briggs , new ignition switch 2022. I think it may be the coil

not the coil. Engines need to turn to start. I might look again at the battery, battery cables for solid connections and no corrosion. Also try it with the spark plug out to be sure that the cylinder isn't full of fuel and is hydrolocking. Battery cables can go bad internally too. Might be time to get the VOM out.

Roger that , pull the plug and spin it over should spin easily, coils have nothing to do with it spinning over or not

I did clean the ends of the cables attached to the battery , they weren't to bad , cleaned the posts and cable with wire brush , I'll check them again tomorrow . I cleaned the other ends last fall when I replaced the solenoid

Would be easier for us if you posted the complete engine number
However if it is an overhead vale engine then the symptoms are classic no decompression .
90% of the time this is because the valve lash on the inlet valve has gotten so big it is defeating the tiny movement caused by the ACR on the other 10% it is because the ACR mechinims on the cam shaft has self destructed .

It could very well be the hydrolocking because I smell gas for a day or two after cutting my lawn. Thank you I'll look into it
