i have a 15r77m seahorse the motor will start with throtle wide open in neutral but when put in gear dies right away. Starts back up but have to keep pushing and pulling choke but again only in neutral. new plugs new carb, getting spark, new fuel pump new gas good mix. From the manual everything is in its place . What could be the problem?
 
Have you checked compression? Have you done a proper spark test? Spark must jump a 3/8" gap...
Is the carb brand new or just one off a different engine?
