    1970 4hp Johnson low compression

    no wars for me... :) I have faith in that little kicker. the compression readings are low yet I have this feeling the measurement process or meter quality is suspect at this point. just me I guess. if the reeds are ok pressure build up in the crankcase should build up enough to work...
