25 Hp Johnson Issue

1 post in this topic

I was running my motor (early 70s 25 hp) last year full speed and had a clip on the carburatuer linkage come off so my motor went from full speed down to nothing imediatley. I had this happen before so I new what the issue was. I placed the clip back on and it imediately ran rough at idle and slow speed (stalls and spits and sputters) but runs fine at higher rpm. Since then it runs good at times and rough sometimes at lower rpm. I took the carb off and tried cleaning anything I could thinking a piece of somthing was dislodged from the sudden change of rpms and did not help. I tried messing with the slow idle adjustment but did little.

Anybody have any ideas of other things to check. I was going to pull the flywheel and look at the points and see if somthing there is whacked. Does anyone know if I need a gear puller to get the flywheel off?

Any help would be appreciated.
