Bought boat, motor and trailer back in Dec. Motor is 1990 johnson 60hp and was no good. Previous owner ran motor without a water impeller KEY so it got too hot. Anyway I bought it for cheap.
I decided to rebuild and this is my first rebuild of a outboard motor. Took tons of pics, notes and used omc instructions.*
Bottom cylinder was sleeved with a new standard piston and the top two cylinders remained as they were .030 over with new rings and rod bearings.
I reassembled the motor and today it cranks perfect but will not start.
Here's the conditions:
compression= 118psi all cylinders
All three spark plugs have spark
Carbs cleaned and floats at 1.375
All carbs bowls fill with fuel
Carbs synchronized the best I could
Primer bulb gets tight no leaks
Fuel pump cleaned and looks good
VRO I assume was removed years ago
All new fuel hose
Fuel primer solenoid cleaned
New battery
Fuel tank drained and using 50:1
New impeller
I'm not convinced that fuel is getting to
the piston. I remove the spark plugs
and they don't seem that wet with fuel.
Where should I start to try and find out
what I'm missing?
Thanks
