Re: Johnson 6hp…won’t start

[sedover]

Back to basics; compression check, spark check (1/4" gap), then the carb. Don’t need J8’s stay with 6’s. If engine runs cold check thermostat.

Remember the crankcase has to suck the fuel air mix in, so, poor compression will make it a hard starter because it is suction on the backside. A worn engine will often need to be wetted down to seal.

Start with the basics first and then proceed. Other little things come into play now that these engines are 40-50 yrs old.
