1989 120hp johnson compression test results good or bad

[Bob427]

i bought this motor as a winter projet to hopefully hang on my boat come spring time

so i took compression today and here are the results
#1 120 #2 120
#3 120 #3 120

all even how ever number two cylinder takes about two times more revolutions to come up to psi


now motor has sat for a long time as it will definatly need carb kits

it does have good blue spark on the spark checker

just wondering if i should be concerned about #2 cylinder


thanks Bob
