ok guys you all know my low n slow project. looking to get more power out of a 20hp johnson. willing to do what ever it takes to get more power out of her. i have a spare power head that i was to build up. also wondering how much i can do to it. i know that there has to be some mods i can do to it. i did put a 35 carb on it but did not seem to do much. now i am looking to do reeds but dont know anything bout them or where to get them. also willing to do compression work on it too any help would be awsome thanks guys
