Hello,
I found this forum and could use some help. I am in the process of trying to get my newly acquired 1959 Johnson 50hp running. I replaced everything I could and clean out the carb. When I try to start it I am getting backfiring and a tiny sputter intermittently but it will not start and run. The plugs are getting a little wet but some of the piston heads look dry. New plugs, new wires, getting a good spark, gas tank valve is open, choke on/off. fresh gas (albeit not 93). At this point I am beginning to thing it has too low of compression.
Can anyone tell me what the compression should be in each cylinder? I am between 75-81 on all cylinders.
what other reasons could it be not starting?
