    Friend of mine has this and wanted the carbs rebuilt, i done them last night and started the boat and at idle and giving trottle sound like its popping thru the exhaust, dumb me should of run the boat before repair, but thats hindsight. It has good compression on all cylinders, getting fuel and ball is stiff. I think its ignition, haven't run spark check yet , the module on top front of engine when i had it unbolted and went to reinstall it's housing sparked when it hit ground, is this normal with key off. Any suggestions would be helpfull or proven patterns of this engine.
